The limbic system is not a single structure but a network of interconnected regions located beneath the cerebral cortex and around the brainstem, roughly between the brainstem a...

A reflex arc is the neural pathway that underlies a reflex action, coordinating a rapid, involuntary response to a stimulus without requiring input from the brain. It enables fa...

A reflex arc is the neural pathway that mediates a reflex action, allowing the body to respond rapidly and automatically to potentially harmful stimuli. It coordinates a swift,...

Acetylcholine neurons are specialized nerve cells that synthesize, store, and release the neurotransmitter acetylcholine to communicate with other neurons, muscles, and glands....

The phrase temporal brain commonly refers to structures within the temporal lobe that support perception, memory, and language. This overview explains what the temporal brain is...

The thalamus is a dual structure of gray matter nuclei deep within the forebrain that primarily relays and modulates sensory signals to the cerebral cortex while regulating cons...

A reflex arc is a neural pathway that produces a rapid, involuntary response to a stimulus without requiring processing by the brain. It coordinates the detection of a change, t...

The nucleus accumbens is a key forebrain structure near the base of the brain that sits at the intersection of motivation, reinforcement, and reward processing. As a central nod...

An efferent response to sensory information is the observable reaction that follows sensory input and is shaped by integration in the central nervous system. In a basic reflex,...

The thalamus is a paired structure of gray matter nuclei near the center of the brain, sitting above the brainstem and beneath the cerebral cortex. Each hemisphere contains a th...
