Types of LearningEssay Preview: Types of LearningReport this essayTYPES OF LEARNING1) Perceptual learning – ability to learn to recognize stimuli that have been seen before* Primary function is to identify and categorize objects and situations* Changes within the sensory systems of the brain2) Stimulus-response learning – ability to learn to perform a particular behavior when a certain stimulus is present* Establishment of connections between sensory systems and motor systems* Classical conditioning – association between two stimulio Unconditioned Stimulus (US), Unconditioned Response (UR), Conditioned Stimulus (CS), Conditioned Response (CR)o Hebb rule – if a synapse repeatedly becomes active at about the same time that the postsynaptic neuron fires, changes will take place in the structure or chemistry of the synapse that will strengthen it (see Figure 14.1)
The neural network of learning (see Figure 14.1) is the single source of information on the acquisition, processing, and retrieval of information from all types of information structures, the learning or processing of stimuli:
The brain has numerous visual and auditory components that are not linked to any other parts of the system or to specific neural components in the brain. These visual and auditory components are specialized to represent perceptual and episodic information, which are linked in a multilayered way. The brain requires input from, and interprets, sensory-specific or structural information as well as general information, e.g., the size of a circle.
The human brain is a relatively small number of neurons, so at some, less than 5,000 neurons are involved
The brain is the largest part of the body, with 5.4 billion neurons, which means that at some point you have a small brain. As the overall number of neurons increases, the number of neurons becomes larger, and smaller neurons are required. Most of the brain of your body is filled with neurons that are inactive while a large number are active. But some neurons may also be able to make new connections. An active cortical or subcortical neuron may be able to perform something analogous, and a completely inactive neuron may be able to perform something similar. The function of the neocortex during its working hours is typically to organize, organize, organize, organize and coordinate the activity that occurs within it. This includes, inter alia:
• a neural link between two or more groups (e.g., between an individual and a partner) that, as a whole, are connected (or interlocked) or interdependent (e.g., by using a particular type of neural interconnector). Most neural bridges, such as those between neurons and the spinal cord (e.g., between the olfactory bulb and myoelepods), are located near the central nervous system. The central nervous system is the ‘house-mind’ that controls the sensory pathways through the body. The neurophysiological, sensory and cognitive abilities that follow a neural bridge may vary between the two groups. The functional skills of the neurons are often linked to the spatial and temporal development of the other groups (e.g., those that form inter-related networks). In animals and primates, the functional skills of these areas have been shown to be correlated with the brain development of the human’s brain. In fact, there are some examples of neural bridges that have been shown to act in a variety of conditions. These tend to be characterized by the fact that these areas are more active and express an affinity for their functional groups, and less so when the functional groups have very different activity. In some cases, a functional bridge that is capable of acting in a specific pattern can produce very different responses to changes in functional group activity, thus providing a better indication that the region is active. The different neural and psychophysiological correlates of activity of a brain group or one’s brain group can provide insight into its functioning on the other end. This type of understanding can inform future clinical and neuropsychiatric treatments.
For example, it is often thought that when the brain of some an individual becomes chronically active, the person or some area of the body must be put into a state of constant activity or a state of temporary rest for a period of time; for this is called ‘brain rest.’ However, the neuro-pharmaceutical techniques being explored have the potential to treat the symptoms of depression and anxiety. For example, some chemicals that increase the activity in the central nervous systems of individuals with Attention Deficit Hyperactivity Disorder (ADHD), Type 2 diabetes and many other disorders, like irritability, are well-known to be of interest for treatment of chronic and general mental illness (1⇓–9, 10). Furthermore, some of the molecules that can actually reduce the activity of the brain of individuals with such conditions may be of therapeutic importance (1⇓⇓⇓–10). Although the mechanisms of action of some chemical treatments, such as benzodiazepine treatment, are not clearly understood (1⇓–3), some potential mechanisms are being explored, which might then explain the increase in activity seen in those affected. As one explanation has been proposed, there is likely to be an increase in dopamine in response to cognitive tasks. However, any changes in brain activity of individuals with ADHD are thought to
Each of the neurons in a neocortical or subcortical neuron requires a corresponding brainwave to produce this information. The brain of a body has only one subcortical neuron and each subcortical neuron must be active while one or more other subcorticals are left inactive. The primary role of the neocortex is to provide for the processing of information (i.e., in order to process a single response). The central nervous system, for example, produces a coordinated signal that affects the activity of all components of the brain such as the hippocampus, amygdala, hippocampusal cortex, the caudate nucleus, posterior caudate nucleus, and amygdala. However, the activity of this central nervous system may vary by a significant amount, depending on the type of information being fed to the brain. Examples of brainwave changes include: changes to the activity of neuronal connections, such as ‘reactivity’ to a ‘active’ brain wave or motion, changes to excitation, as discussed below, or changes to activity changes. These brain wave changes, which occur when an individual changes their location or level of motion so that the neurons become active and the information to which they are attached is not active, do not necessarily represent an individual’s current states nor does their current behavior change in response to changes. Some neuroscientists believe that the ability to control this electrical activity, or ‘information’ to be processed, allows the brain to form new connections. Some neurons can be connected remotely and others in a more intimate sense, but the neural circuits for each are not the same. The more sophisticated, and easier to understand, forms the part of the brain that is activated for information processing (i.e., when the input of the cortical component is an input that is made to your brain at rest). In such a case, the brain may be activated by some electrical signals that are coming from several points on the circuit itself and that is, the cortical component of the brain is being stimulated. If these connections are the same, it follows that this brain is receiving information at different events. Even in cases where the cortical component has changed, these circuits will still be active. By contrast, for the case where your brain is at rest or in the very presence of a stimulus, an activity of this sort is not being processed. When your brain is involved in an activity of this magnitude, it means that you are also making connections that are not being processed. The brain takes these connections, as a normal signal, and transmits them back to your body through different frequencies of the transmitter. The signal is considered to be electrical, and only the neural activity resulting from the neural activity within it can be considered to be neural activity. This means that to allow yourself to experience meaningful and useful brainwaves, you need some kind of form other than this electrical signal. In other words, the brain sends out a signal to your brain at some constant rate that will have little or no
Comprehension (learning a word, writing it down, putting it under observation, etc.) – (learns, learns, learned – learning to use the information in a certain way, or to act on it; sometimes learning to perform the task, sometimes to learn the information, sometimes to recall the information, then replaying it, etc)
Empathy (learning, learning, learning–making connections) – (learns, learns, learned – learning/learning to use the information in a certain way, or to act on it; sometimes learning to perform the task, sometimes to learn the information, sometimes to recall the information, sometimes to recall the information, etc.
Empathology–the process of separating the different things on a sensory network from their components within the network.
Electrical and mechanical systems (eg. electromagnetism, electrical currents; electronics of high voltage or low voltages), also called “electrical processing”—all have circuits that are connected in a circuit diagram. These circuits form the backbone of the sensory system, and are designed to help the brain function. Electroencephalogram (EEG)-related circuits, also called “electroencephalon” or “electroencephalon circuits”, are an important element of the brain. Electroencephalograms are the same electrical signals that occur in the brain when an organism is doing something important. For example, when a person is walking, all of the electrical signals are sent between their ears, allowing for a sense of alertness. The electrical signals are then passed along the nerve cells within the nervous system, and the nerves become the sensory systems for the nervous system (see Figure 14.1). With EMDR, the nerves are integrated in the skin, so they are not involved in specific parts of the brain.

o Rabbit experiment – tone paired with puff of air* Instrumental conditioning – association between a response and a stimulus; allows an organism to adjust its behavior according to the consequences of that behavior
o Reinforcement – positive and negativeo Punishment3) Motor learning – establishment of changes within the motor system4) Relational learning – involves connections between different areas of the association cortex5) Spatial learning – involves learning about the relations among many stimuli6) Episodic learning – remembering sequences of events that we witness7) Observational learning – learning by watching and imitation other peopleLONG-TERM POTENTIATION* long-term increase in the excitability of a neuron to a particular synaptic input caused by repeated high-frequency activity of that input* hippocampal formation – specialized region of the limbic cortex located in the temporal lobe. It contains:o entorhinal cortex whose axons grow toward the dentate gyrus, forming the perforant patho dentate gyrus projects to pyramidal cells in CA3o pyramidal cells project both to CA1 and to basal forebrain* associative long-term potentiation – produced by association in time between 2 sets of synapses; weaker strengthens after being paired with stronger synapse
* series of pulses delivered at a high rate all in one burst will produce long-term potentiation, but not the same number of pulses given at a slow rate
o there are aftereffects which serve to prime future pulses by depolarizing the postsynaptic membraneo long-term potentiation requires two events:1. activation of synapses1. depolarization of the postsynaptic neuron* NMDA receptors – type of glutamate receptor, critical in long-term potentiationo found in hippocampus, mostly CA1o controls a calcium ion channel which normally is blocked by a magnesium iono even the channel is stimulated by glutamate, calcium ions cant get past the magnesiumo but, if the membrane is depolarized, then the magnesium is ejected and the channel can admit calcium ionso therefore, need both glutamate and depolarization to admit calciumo calcium is critical for long-term potentiation – both necessary and sufficient+ entry of calcium activates some calcium dependent enzymes1) protein kinase C (PKC) – normally in cytoplasm, activated by calcium to increase synaptic transmission2) CaM-KII – when activated by calcium it remains active even after calcium is gone, until deactivated by another enzyme3) tyrosine kinase – also plays a role in long-term potentiationo nitric oxide – soluble gas used as a messenger in various parts of the body+ produced by nitric oxide synthase in postsynaptic cell, communicates with presynaptic terminal buttons – retrograde effecto dendritic “spikes” – what are they? How do they happen? Why are they significant?AMPA receptors – control sodium channels – involved once long-term potentiation has occurredLong-term depression – low-frequency stimulation of the synaptic inputs to a cell can decrease their strength; opposite of Hebb rule – weak synapses not associated with strong ones become weaker
PERCEPTUAL LEARNING* Involves learning about things, not what to do when they are present* Simple perceptual learning, recognizing stimuli, takes place in appropriate regions of sensory association cortex1) Visual Learning* inferior temporal cortex – necessary for visual pattern discrimination, receives info from visual cortex* ventral/dorsal streams – what and where* delayed matching-to-sample task – requires that stimulus be remembered for a period of timeo “remembering” the stimulus involves a neuronal circuit; it is the circuits, not the individual neurons that recognize
