the outer layer of neural tissue in the parietal lobe involved in sensory processing and spatial awareness

a chemical substance that transmits messages from a neuron to another one or to a muscle

the process by which new neurons are generated in the brain, occurring primarily during prenatal development but also continuing into adulthood in certain brain regions

a mental condition that is not caused by organic disease in which one is constantly anxious, worried, and stressed

a scientist who studies the structure, function, and disorders of the nervous system, including the brain and spinal cord

a neurological phenomenon where stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway

a physical perception caused by an outside stimulus or something being in touch with the body

the temporary storage of information that is currently being used or actively processed by the brain, typically for a few seconds to a few minutes

the branch of medicine and physiology dealing with the endocrine system that controls the hormones in one's body

a hormone produced by the pineal gland that regulates sleep-wake cycles and promotes restful sleep

a hormone produced mainly by the stomach that stimulates appetite and regulates hunger

a hormone produced primarily by fat cells that helps regulate energy balance by inhibiting hunger and promoting feelings of fullness

a hormone primarily responsible for female reproductive development and regulation

a neurotransmitter primarily found in the brain and gastrointestinal tract that plays a key role in mood regulation, appetite, sleep, and various physiological functions

a compound released by cells in response to injury, allergy, or immune reactions, causing inflammation, itching, and other allergy symptoms

a biochemical assembly that transports fats in the bloodstream, composed of proteins and lipids

a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter

a small protein that regulates immune responses and cell communication in the human body

having the ability to restrain, limit, or suppress activity or function
