The consensus among neuroscientists is that the basis of learning and memory creation lies in changes in electrically active nerve cells, called neurons, and the connections between them, the synapses. Although neurons come in many diverse shapes, a stereotypical example of two neurons is shown in Figure 1.

Abstract. Three stages of visual processing determine how internal noise appears to an external observer: light adaptation, contrast gain control and a postsensory/decision stage.

These stages in order include attending, encoding, storing, retrieving. Information processing also talks about three stages of receiving information into our memory. These include sensory memory, short-term memory, and long-term memory.

Neurons. The basic functional unit of the brain is the neuron. Its functional role is to send and receive the electrical impulses that communicate messages about sensory, motor, and cognitive events throughout the brain.

Neurons send signals to other neurons via specialized contacts known as synapses. The most common type of synapse in the nervous system is known as a chemical synapse. Typically a chemical synapse occurs between the axon terminal of the neuron sending the message, and the dendrite of the neuron receiving the message.

At a synapse, one neuron sends a message to a target neuron—another cell. ... Other synapses are electrical; in these synapses, ions flow directly between cells. At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters.

In summary, the most brilliant similarity between both these ways of communications is that they both deal with transferring and receiving information. In addition to that, none of them, verbal and non-verbal communication, are not connected to the brain.

Neurons, or nerve cells that carry nerve impulses, are made up of the cell body, the axon, and several dendrites. Signals move across the synapse, the place where the axon of one neuron meets the dendrite of another, using chemicals called neurotransmitters.

While Neural Networks use neurons to transmit data in the form of input values and output values through connections, Deep Learning is associated with the transformation and extraction of feature which attempts to establish a relationship between stimuli and associated neural responses present in the brain.

Information flows through a neural network in two ways. When it's learning (being trained) or operating normally (after being trained), patterns of information are fed into the network via the input units, which trigger the layers of hidden units, and these in turn arrive at the output units.

This axon hillock is the site of summation for incoming information. At any given moment, the collective influence of all neurons that conduct impulses to a given neuron will determine whether or not an action potential will be initiated at the axon hillock and propagated along the axon.
