Miscellaneous
The oldest part...and what connects the brain to the spinal cord.
This lobe is responsible for vision.
Occipital
This structure regulates basic life functions like heartbeat and breathing.
Medulla
This area in the left frontal lobe helps produce speech.
Broca's Area
The branch-like parts of a neuron that receive signals from other cells.
Dendrites
This type of cell supports, nourishes, and protects neurons.
Glial Cells
This structure is responsible for forming new memories.
Hippocampus
This lobe processes touch, pain, and temperature.
Parietal
This part helps coordinate balance and movement.
Cerebellum
This area in the left temporal lobe helps understand language.
Wernicke's Area
This fatty layer speeds up electrical signals traveling down the axon.
What is the myelin sheath?
These specialized neurons carry messages from your senses to the brain and spinal cord.
Sensory Neurons
This bundle of nerves allows communication between the brain's hemispheres.
Corpus Callosum
This lobe helps with hearing and language understanding.
Temporal
This "relay station" directs messages to the sensory areas.
Thalamus
The brain’s ability to adapt or reorganize after damage.
Plasticity
This is the name for a neuron's "resting" state, when it has a negative charge inside.
Resting potential
These neurons carry messages from the brain and spinal cord to your muscles.
Motor Neurons
This technique shows brain activity using blood flow.
fMRI
This strip in the frontal lobe controls voluntary movement.
Motor cortex
This gland, often called the "master gland," is part of the endocrine system.
Pituitary gland
This surgery, used to treat severe epilepsy, involves cutting the corpus callosum.
Split-brain surgery
This term refers to the minimum level of stimulation needed to trigger a neural impulse.
Threshold
These neurons connect sensory and motor neurons in the brain and spinal cord.
Interneurons
This system, including the amygdala and hypothalamus, controls emotions and drives.
Limbic System
Damage to this lobe may result in personality changes and loss of impulse control.
Frontal Lobe
This structure, located above the brainstem, regulates alertness and arousal.
Reticular Formation
People with this condition caused by left hemisphere damage can speak fluently but use nonsensical words.
Wernicke's Aphasia
This happens when a neuron fires and positive ions flood inside, changing the electrical charge.
Depolarization
This is the path a nerve impulse takes during a quick, automatic response like pulling your hand from a hot stove.
