Relay interneurons have long axons and connect circuits of neurons in one region of the brain with those in other regions. [5] However, interneurons are generally considered to operate mainly within local brain areas. [6] The interaction between interneurons allows the brain to perform complex functions such as learning and decision-making.
Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the synaptic gap. Neurons are the main components of nervous tissue in all animals except sponges and placozoans.
Association fibers are axons (nerve fibers) that connect cortical areas within the same cerebral hemisphere. [1]In human neuroanatomy, axons within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers, and commissural fibers. [1]
A Hopfield network (or associative memory) is a form of recurrent neural network, or a spin glass system, that can serve as a content-addressable memory.The Hopfield network, named for John Hopfield, consists of a single layer of neurons, where each neuron is connected to every other neuron except itself.
The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.
In the neocortex, projection neurons are excitatory neurons that send axons to distant brain targets. [2] Considering the six histologically distinct layers of the neocortex, associative projection neurons extend axons within one cortical hemisphere; commissural projection neurons extend axons across the midline to the contralateral hemisphere ...
Associative sequence learning (ASL) is a neuroscientific theory that attempts to explain how mirror neurons are able to match observed and performed actions, and how individuals (adults, children, animals) are able to imitate body movements. The theory was proposed by Cecilia Heyes in 2000.
The stability analysis of a BAM is based on the definition of Lyapunov function (energy function) , with each state (,). When a paired pattern ( A , B ) {\displaystyle (A,B)} is presented to BAM, the neurons change states until a bi-directionally stable state ( A f , B f ) {\displaystyle (A_{f},B_{f})} is reached, which Kosko proved to ...
