Definitions:

Animal Experiments

Research studies conducted on non-human animals to investigate biological, behavioral, or psychological phenomena.

Dendrites

Dendrites are the branching extensions of a neuron that receive signals from other neurons or sensory stimuli, playing a critical role in the transmission of neural signals.

Neurotransmitters

Chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.

Neurons

Neurons are the basic working units of the brain and the entire nervous system, functioning to process and transmit information through electrical and chemical signals.
