Neurons form complex biological neural networks through which nerve impulses (action potentials) travel. Neurons do not touch each other (except in the case of an electrical synapse through a gap junction); instead, neurons interact at close contact points called synapses. A neuron transports its information by way of an action potential.
Neural Communication and Integration: Postsynaptic potentials allow neurons to integrate inputs from thousands of synapses, functioning as a "decision-making unit" within the brain. [ 7 ] Learning and Memory: Neuroplasticity is the key mechanism whereby learning and memory happens.
Neurotransmitter (NT) receptors are located on the surface of neuronal and glial cells.At a synapse, one neuron sends messages to the other neuron via neurotransmitters.. Therefore, the postsynaptic neuron, the one receiving the message, clusters NT receptors at this specific place in its memb
Carry messages between neurons via influence on the postsynaptic membrane. Have little or no effect on membrane voltage, but have a common carrying function such as changing the structure of the synapse. Communicate by sending reverse-direction messages that affect the release or reuptake of transmitters.
Neurons form networks through which nerve impulses travels, each neuron often making numerous connections with other cells of neurons. These electrical signals may be excitatory or inhibitory, and, if the total of excitatory influences exceeds that of the inhibitory influences, the neuron will generate a new action potential at its axon hillock ...
The first phase of synaptic potential generation is the same for both excitatory and inhibitory potentials. As an action potential travels through the presynaptic neuron, the membrane depolarization causes voltage-gated calcium channels to open.
Chemical synapses are biological junctions through which neurons' signals can be sent to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form circuits within the central nervous system. They are crucial to the biological computations that underlie perception and thought.
Neural coding (or neural representation) is a neuroscience field concerned with characterising the hypothetical relationship between the stimulus and the neuronal responses, and the relationship among the electrical activities of the neurons in the ensemble.
