Unit 1-3 Exam
Chapters 3-4: Biology and Behavior + Consciousness
| Term | Definition |
|---|---|
| Define consciousness; in what ways can we control consciousness (or not) | a moment-to moment subjective experience of the world (individualistic) - ways to control it through meditation+flow+priming - cannot control consciousness through sleep+automatic processing+exogenous attention+hypnosis |
| Mirror test/rouge test | a study where it demonstrates when we fully gain self-awareness in consciousness |
| Priming | occurs when a response to a stimulus is influenced by recent experiences w/ that stimulus --> ex. the rearrangement of words class experiment |
| Sleep stages and cycles | 1. Light Sleep 2. Deepening but not consistent 3+4. Deep Sleep REM Sleep |
| Light Sleep | alpha waves; easily awaken |
| Deepening but consistent | sleep spindles+K-complexes ; less sensitive to external stimuli |
| Deep Sleep | slow wave sleep; delta waves; mind still evaluates info on danger |
| REM Sleep | paradoxial sleep: paralyzed body w/ active brain; occurs after 90 minutes; cycle repeats |
| Purposes of sleep | restoration, avoiding danger at certain times of the day, facilitation of learning |
| Flow | a state of mind where a person find themselves fully immersed in an activity that increase their mood+health; makes them lose track of time |
| Sympathetic nervous system | a division of the autonomic nervous system that prepares the body for action (fight or flight) |
| Parasympathetic nervous system | a division of the autonomic nervous system that returns organs to resting state |
| Main ability/function associated with hippocampus | - a subcortical structure that associates with memory |
| Main ability/function associated with Broca's | - a small portion of the left frontal region of the brain that is associated with language production --> Broca’s aphasia: speech impaired in some way; Broken sentences but comprehendible |
| Main ability/function associated with Wernicke's | - region of the brain that contains motor neurons involved in the comprehension of speech -->Wernicke’s aphasia: Sentences but not coherent |
| Patient H.M | Hippocampus (associated with memory: storing long term memories) removed→ could not remember anything - Still had abilities in skill learning - Mirror tracing |
| Split Brain Surgery Results | corpus callosum is cut; two hemispheres cannot communicate each other - left: language - right: spatial relationship |
| Neural Brain Plasticity | the brain's ability to change in response to experience/injury + activates neurogenesis |
| Action Potential | neural firing along the axon |
| Names and functions of 4 lobes of cortex and cerebellum | Frontal: social behavior, planning, personality memory Temporal: auditory information, memory Parietal: spatial relationships Occipital: visual information cerebellum: motor skills |
| Names and functions of parts of neuron | Dendrites, Cell Body, Axons, Myelin Sheath, Nodes of Ranvier, Terminal Buttons, Synapse |
| Dendrites | detect chemicals |
| Cell Body | info received via dendrites |
| Axons | info (neurotransmitters) travels along this |
| Myelin Sheath | glial cells that grow along the axon in short segments |
| Nodes of Ranvier | short exposed fragments of axon |
| Terminal Buttons | chemical communication occurs |
| Synapse | presynaptic sends neurotransmitters to postsynaptic |
| insula | part of the cerebral cortex - known for taste, pain+empathy, perception of bodily states |
