Psy Flashcards
sbranches at the end of neurons that receive signals from other neurons.
Dendrites
,the large central region of a neuron that performs the basic activities, including the production of energy, to keep the neuron functional.
cell body (soma)
the release, or firing, of an electrical impulse that travels through the axon.
action potential
- : part of the temporal lobe specifically involved in understanding speech.
- dysfunction in understanding or creating coherent speech, caused by damage to Wernicke’s area.
- Wernicke’s area
2. Wernicke’s aphasia
the ability of the brain to adapt its structure or function in response to damage or experience.
Plasticity
- the brain and the spinal cord. All communication with the brain must move through the
- the neurons that connect the central nervous system to other parts of the body.
central nervous system
peripheral nervous system
.is the part of the peripheral nervous system that connects the central nervous system to the parts of the body you control voluntarily.
1.One you think about the other you dont
1.Somatic nervous system/ autonomic nervous system
Founder of clinical neuropsychology, proven to be an essential key in it’s development.Studied memory and damage to temporal lobes, mapped the function of areas of the frontal lobe, determined the lateralization of function in the hemispheres, and demonstrated plasticity after damage. She proved that there are different memory systems,
Brenda Milner, Ph.D.
the cells that facilitate communication within the nervous system.
Neurons
the part of the neuron that carries information toward other neurons.
Axon
a protective sleeve of fatty material that surrounds the axon
myelin sheath
a gap between two connecting neurons
Synapse
chemical messengers that travel across synapses from one neuron to the next
neurotransmitters
drugs enhance the impact of a neurotransmitter
agonist
Other drugs interfere with the impact of a neurotransmitter.
antagonist
is the part of the brain that connects to the spine and controls the functions most essential to staying alive
Brain stem
the brain’s main sensory processing center, located near the center of the brain. Directs the information you take in through your eyes, ears, mouth, and skin to other parts of your brain for further processing.
Thalamus
a cluster of brain areas involved primarily in emotion.: fleeing, fighting, feeding, and, um, sexual intercourse
Limbic system
- Is the part of the limbic system involved in maintaining steadiness in bodily functions
- is the part of the limbic system involved in memory, especially spatial memory and long-term memory.
- is the part of the limbic system involved most directly in emotion, especially fear.
- hypothalamus
- hippocampus
- amygdala
Is the upper front part of the brain, which consists of two hemispheres and is involved in sophisticated, often uniquely human, abilities.
Cerebrum (forebrain)/Cerebral cortex
Your left cerebral hemisphere is paired with the right half of your body, and your right cerebral hemisphere is paired with the left half of your body. The bundle of neurons that connects and allows communication between the two cerebral hemispheres.
- Right cerebral hemisphere
- left cerebral hemisphere
- corpus callosum
- is involved in complex thinking tasks, planning, and other advanced functions, most of which are unique to humans.
- is involved in touch and perception.
- is involved in hearing and speech production.
- is involved in vision
- frontal lobe
- parietal lobe
- temporal lobe
- occipital lobe
- the strip of brain matter near the back of the frontal lobe involved in voluntary movement.
- a strip of brain matter near the front of the parietal lobe involved in receiving information from the senses.
motor cortex and somatosensory cortex
- a part of the left side of the frontal lobe heavily involved in speaking.
- is the speech dysfunction caused by damage to Broca’s area.
- Broca’s area
2. Broca’s aphasia
