Study Notes
Brain Anatomy and Function
- Gyri are the ridges on the brain's surface, composed of white matter core and gray matter outer area.
- Sulci are grooves between gyri, varying in depth and dividing regions of the brain.
- Fissures are deeper grooves separating brain lobes; notable ones include the longitudinal and lateral fissures.
- The auditory association cortex processes sounds and gives meaning to auditory information.
- Frontal lobes handle higher mental processes, decision-making, and fluent speech production.
- The motor cortex sends commands to the somatic nervous system's muscles.
Language Disorders
- Broca's aphasia results from damage to Broca’s area, impairing speech fluency and pronunciation.
- Wernicke’s aphasia, linked to damage in Wernicke’s area, impairs understanding and meaningful language production.
Cognitive Processing
- Top-down processing utilises prior experiences and expectations to shape perceptions.
- Bottom-up processing starts with sensory receptors, building up to brain integration of sensory data.
Memory and Learning
- People can forget up to 90% of learned information within 30 days.
- Reaction time measures decision-making speed in response to stimuli, with simple reaction time assessing immediate responses.
- Cognitive psychology studies mental processes and their characteristics.
Cognitive Psychology History
- Early 1800s beliefs claimed the mind can't be studied scientifically.
- 1868: Franciscus Donders conducted the first cognitive psychology experiment on decision-making.
- 1950: The cognitive revolution shifted focus from behaviorism to internal mental processes.
- B.F. Skinner's operant conditioning discusses the effects of reinforcement on voluntary behavior.
Brain Communication and Functions
- The corpus callosum connects the left and right brain hemispheres, facilitating contralateral communication.
- The cerebral cortex is a thin layer of gray matter covering the brain’s surface, crucial for various brain functions.
- Neurons transmit electrical signals, with synapses being junctions between neurons for communication.
Neurotransmitters
- Acetylcholine plays a vital role in memory, attention, and motor functions.
- Dopamine is tied to attention, reward, learning, and regulating impulsivity.
- GABA is crucial for inhibitory actions in the brain.
Neuroimaging Techniques
- Neuroimaging techniques include EEGs for electrical brain activity and PET scans for physiological functioning through monitoring blood flow.
- Postmortem studies analyze brain function and damage after death, providing insights into speech production and other functions.
Additional Notes
- Research indicates relationships between specific brain damage and speech/language loss.
- Memory difficulties, such as in Alzheimer’s, can be due to low acetylcholine levels in the brain.
