Neuronal Communication

Neuronal communication refers to the process by which neurons transmit and receive information through electrical and chemical signals. This process involves the release of neurotransmitters from the axon terminal of one neuron, which then bind to receptors on the dendrites of another neuron, allowing for the exchange of information. Understanding neuronal communication is crucial in Psychology, as it underlies various cognitive functions, including learning, memory, and behavior.

Overview

Neuronal communication is a complex process that involves the transmission of signals between neurons through electrical impulses and chemical messengers called neurotransmitters. Understanding this process is crucial for grasping how the nervous system operates, influencing everything from reflexes...

Key Terms

Neuron
A specialized cell that transmits nerve impulses.

Example: Motor neurons control muscle movements.

Action Potential
A rapid rise and fall in voltage across a neuronal membrane.

Example: Action potentials allow signals to travel along axons.

Synapse
The junction between two neurons where communication occurs.

Example: Neurotransmitters are released into the synapse.

Neurotransmitter
Chemicals that transmit signals across a synapse.

Example: Dopamine is a neurotransmitter involved in reward.

Receptor
A protein on a cell that binds to specific neurotransmitters.

Example: Dopamine receptors respond to dopamine.

Dendrite
The part of a neuron that receives signals from other neurons.

Example: Dendrites collect information from other neurons.
