CogNeuro Chapter 1
| Term | Definition |
|---|---|
| Penfield findings after electric stimulation + importance | mapping structure to function: patients saw things that weren't there because the brain was being stimulated |
| Brain definition | physical stimulus made up of billions of nerve cells that control all bodily functions of human |
| Mind definition | intellectual and psychological phenomena of a human |
| Cognitive neuroscience definition | field that tries to explain cognition in terms of brain-based mechanisms |
| Macroneural | macroscopic (larger) regions of the brain and their interactions represent or encode cognitive processes (brain imaging) |
| Microneural | system of microscopic (smaller) neurons and how their interactions represent or encode cognitive processes |
| Which (macroneural or microneural) applies most to study of cogneuro? | macroneural |
| Cognition definition | higher mental processes |
| 3 examples of cognition | perceiving, speaking, reading |
| Conscioussness definition | state of awareness of one's own existence and experience |
| Mind-Body Problem definition | philosophical question of science; hwo the physical body can give rise to non-physical thought/emotion/cognition |
| Dualism | by Descartes; body and mind are separate and interact; body = material machine, mind = nonmaterial and doesn't follow laws of physics |
| Dual-Aspect | mind and body/brain are two levels of explanation for th esame thing; one underlying dimension is responsible for both |
| Reductionism | mind eventually explained soley in terms of physical/biological theory; mind can be reduced to the brain/body |
| Monism | by Thales; everything reduced to one substance |
| Easy problem of cogneuro related to mind-body problem | correlating brain with mental states |
| Hard problem of cogneuro related to mind body problem | explaining how physical processes in the brain give rise to consciousness |
| Phrenology definition | pseudoscience; functional specialization; differences in personality traits manifest in differences in cortical size and bumps on the skull; lots of division of psych traits |
| Why is phrenology important despite being debunked? | idea that different regions of the brain serve different functions is supported and called functional specialization |
| Functional specialization definition | different parts of cortext (outer layer) serve different functions |
| Computer metaphor for cognition | think of mind as a series of routines, like in computers |
| information-processing model | human cognition like a computer; don't make direct reference to the brain |
| connectionist model | mathematical (computational) in nature but don't involve serial processing and discrete routines; these computational models mirror how neurons wokr |
| temporal resolution definition | time resolution; how good the measurement is/how well it can track the timing |
| spatial resolution definition | where in the brain the activity is |
| what does invasiveness mean? | yeah idk |
| localization problem definition | oversimplification; idea that sometiems it seems like we are saying "x marks the spot" with brain processes and fucntions |
| binding problem definition | opposite of localization problem; how items that are encoded by distinct brain circuits can be combined for perception, devision, and action |
