Cerebral Cortexi. Frontal Lobeii. Parietal Lobeiii. Occipital Lobeiv. Temporal LobeIII. Brain’s PlasticityCurrent LectureI. What Affects Emotions?a. Amygdalai. Related to fear, angerii. Part of the brainiii. Injuring it but putting lesions on it reduces fearb. Hypothalamusi. Controls endocrine systemii. Gauges if temperature, calcium, glucose, thirst, and sex glands are all correctiii. Directs maintenance issues and controls emotionsiv. Sends messages to the pituitary and the pituitary fixes the issuesc. HippocampusThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.i. In charge of any new memoriesii. Processes new memoriesiii. For an experiment, a person had their hippocampi taken out and now they do not have any new memoriesII. Cerebral Cortexa. Most recently developed part of the brainb. Is a thin layer of that cover the majority of the brainc. Has four lobes:i. Frontal Lobe- Located in the forehead region- Motor Cortex: sends signals to muscles- Makes executive decisions: judgment and decision making - In the Frontal Lobe, there is an area of the brain that was discovered and named Broca’s areao This region allows someone to comprehend language, but not speak itii. Paiii. rietal Lobe- Located in the top to the rear of the head- Sensory cortex: aids in the perception of space and sizeiv. Occipital Lobe- Located in the back of the head- Responsible for visionv. Temporal Lobe- Located in the side of the head (temples/temporal)- Responsible for hearing- An area was discovered in this region that allows for the speaking of language but not the comprehension- Area called Wernicke’s area.III. Brain’s Plasticityo Neural plasticity: the nervous system’s ability to changeo Learning requires a change in brain structureo Hippocampus is in charge of learning and memoryo Stem cells: cells that have the potential to become specialized cellso Neurogenesis: production of new neurons in the adult brain Standard environments grow short neurons Enriched environments allow for the growth of more branched and expanded
