PSYC 107 1nd Edition Lecture 7 Outline of Last Lecture I Neurotransmitters II Parts of the Nervous System III Nervous Systems IV Brain Outline of Current Lecture I What Affects Emotions II Cerebral Cortex III i Frontal Lobe ii Parietal Lobe iii Occipital Lobe iv Temporal Lobe Brain s Plasticity Current Lecture I What Affects Emotions a Amygdala i Related to fear anger ii Part of the brain iii Injuring it but putting lesions on it reduces fear b Hypothalamus i Controls endocrine system ii Gauges if temperature calcium glucose thirst and sex glands are all correct iii Directs maintenance issues and controls emotions iv Sends messages to the pituitary and the pituitary fixes the issues c Hippocampus These 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 memories ii Processes new memories iii For an experiment a person had their hippocampi taken out and now they do not have any new memories II Cerebral Cortex a Most recently developed part of the brain b Is a thin layer of that cover the majority of the brain c 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 area o This region allows someone to comprehend language but not speak it ii Pa iii rietal Lobe iv v III Located in the top to the rear of the head Sensory cortex aids in the perception of space and size Occipital Lobe Located in the back of the head Responsible for vision 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 Brain s Plasticity o Neural plasticity the nervous system s ability to change o Learning requires a change in brain structure o Hippocampus is in charge of learning and memory o Stem cells cells that have the potential to become specialized cells o 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 neurons
