Branch of neuroscience that focuses on biological bases of psychological processes, behavior, and learning | Biological Psych/Behavioral Neuroscience |
Branch-like structures of a neuron that receive messages from other neuron. Attached to cell body | Dendrites |
A sense of balance in the nervous system | Homeostasis |
Bundles of axons coated in myelin that travel together through peripheral nervous system (body) | Nerves |
Schwann Cell | Self-repairing glial cell |
Relative balance of electrical charges when ions are at rest | Electrostatic Pressure |
Axon closest to the soma | Axon hillock |
Nerves | Tracts |
Chemical found in synaptic vesicles that, when released, have an effect on the next cell | Neurotransmitters |
Presynaptic membrane | Ending vesicles of axon |
Surface of the dendrite next to the axon | Postsynaptic membrane |
Proteins on surface of dendrites or cells of muscles/glands, shaped to fit only certain neurotransmitters | Receptor sites |
Synapse at which a neurotransmitter causes the receiving of a cell | Excitatory synapse |
First neurotransmitter to be identified. Found at synapses between neurons and muscle cells | Acetycholine ACh |
Antagonist | Blocked ACh |
Ability of brain to change connections among it's neurons | Synaptic plasticity |
Parkinson's | Too little dopamine |
Schizophrenia | Too much dopamine |
Overactivation, neuronal damage, cell death after stroke, head injury, degenerative diseases (Alz) | Too much glutamate |
Most common neurotransmitter producing inhibition in brain | Gamma-aminobutyric acid (GABA) |
Angonist | Alcohol & GABA |
Pain controlling chemicals in body | Endorphins |
Body does not produce endorphins | Heroin and morphine |
Process by which neurotransmitters are taken back into the synaptic vesicles after action potential | Reuptake |
Blocks reuptake process | Cocaine |
The process of (instead of reuptake) ACh being broken apart by an enzyme, cleaning the synaptic gap quickly | Enzymatic degradation |
Mimic/enhance effects of neurotransmitters | Drugs acting as agonists |
Agonists for GABA | Anti-anxiety medications (benzodiazepines) |
Blocking or reducing a cell's responses to the action of other chemicals or neurotransmitters | Drugs acting as antagonists |
The portion of the vertebrate nervous system consisting of the brain and spinal cord | Central nervous system |
The section of the nervous system lying outside the brain and spinal cord | Peripheral nervous system |
The part of the nervous system of vertebrates that controls involuntary actions of the smooth muscles and heart and glands | Autonomic nervous system |
Carries sensory information and controls movement of the skeletal muscles | Somatic nervous system |
Carries messages from senses to CNS | Sensory system/pathway (afferent) |
Carries messages from CNS to muscles and glands | Motor system/pathway (efferent) |
Afferent neurons in pain | Access spinal cord |
Efferent neurons in pain | Neurons exiting |
The development of nerve tissues | Neurogenesis |
First large swelling at top of spinal cord, responsible for breathing, swallowing, heart rate | Medulla |
The two sections of the cortex on the left and right sides of the brain | Cerebral hemispheres |
Contains somatosensory cortex | Parietal lobes |
Area of neurons at the front of the parietal lobes on either side of brain. Processes info from skin and internal body receptors touch, temp, and body position | Somatosensory cortex |
The auditory word center; located in the posterior part of the superior temporal convolution in most people | Wernicke's area |
Aphasia characterized by fluent but meaningless speech and severe impairment of the ability understand spoken or written words | Wernicke's aphasia |
Damage to right parietal and occipital lobes will ignore everything in left visual field (most common scenario) | Spatial neglect |
