1 1 © 1999 The Ohio State University & Worth Publishers. Introductory Psychology Lectures A series of PowerPoint lectures to accompany the introductory psychology textbooks offered by Worth publishers Editor: Harvey G. Shulman, Ph.D. Subcortical Structures Joe Williams The Ohio State University Department of Psychology

2 2 © 1999 The Ohio State University & Worth Publishers. Subcortical Brain Structures zSubcortical - underneath the cortex yhypothalamus and pituitary ybasal ganglia ylimbic system yhindbrain and brainstem structures

3 3 © 1999 The Ohio State University & Worth Publishers. Hindbrain Structures zCerebellum zBrainstem ymedulla yreticular formation ypons

4 4 © 1999 The Ohio State University & Worth Publishers. Cerebellum zCoordinated, rapid voluntary movements ye.g., playing the piano, kicking, throwing, etc. zLesions to cerebellum yjerky, exaggerated movements ydifficulty walking y loss of balance y shaking hands

5 5 © 1999 The Ohio State University & Worth Publishers. Medulla zBreathing zHeart rate zDigestion zOther vital reflexes yswallowing ycoughing yvomiting ysneezing

6 6 © 1999 The Ohio State University & Worth Publishers. Reticular Formation zNetwork of neurons in the brainstem (and thalamus) zSleep and arousal zAttention

7 7 © 1999 The Ohio State University & Worth Publishers. Pons zHelps coordinate movements on left and right sides of the body ye.g., postural reflexes which help you maintain balance while standing or moving

8 8 © 1999 The Ohio State University & Worth Publishers. Thalamus zRelay station in brain zProcesses most information to and from higher brain centers

9 9 © 1999 The Ohio State University & Worth Publishers. The Limbic System zHypothalamus zAmygdala zHippocampus

10 10 © 1999 The Ohio State University & Worth Publishers. Hypothalamus zContains nuclei involved in a variety of behaviors y sexual behavior yhunger, thirst ysleep ywater and salt balance ybody temperature regulation ycircadian rhythms yrole in hormone secretion

11 11 © 1999 The Ohio State University & Worth Publishers. Hypothalamus and Hunger zDamage to the ventromedial hypothalamus leads to overeating

12 12 © 1999 The Ohio State University & Worth Publishers. Hypothalamus and Hormones zHypothalamus releases hormones or releasing factors which in turn cause pituitary gland to release its hormones

13 13 © 1999 The Ohio State University & Worth Publishers. Amygdala zInputs come from all senses zAmygdala reads emotional significance of inputs zOutput influences such functions as heart rate, adrenaline release

14 14 © 1999 The Ohio State University & Worth Publishers. Amygdala and Emotion zIdentify emotion from facial expressions z Amygdala damage makes this task difficult

15 15 © 1999 The Ohio State University & Worth Publishers. Hippocampus zImportant in forming new memories

16 16 © 1999 The Ohio State University & Worth Publishers. Basal Ganglia zSlow, deliberate movements zParkinsons disease is the result of abnormalities in the basal ganglia

17 17 © 1999 The Ohio State University & Worth Publishers. Dopamine zInvolved in movement, attention and learning zDopamine imbalance also involved in schizophrenia zLoss of dopamine- producing neurons is cause of Parkinsons disease

18 18 © 1999 The Ohio State University & Worth Publishers. Parkinsons Disease zResults from loss of dopamine-producing neurons in the substantia nigra zSymptoms include ydifficulty starting and stopping voluntary movements ytremors at rest ystooped posture yrigidity ypoor balance

19 19 © 1999 The Ohio State University & Worth Publishers. Parkinsons Disease zTreatments yL-dopa ytransplants of fetal dopamine-producing substantia nigra cells yadrenal gland transplants yelectrical stimulation of the thalamus has been used to stop tremors
