Substantia nigra
Inferior colliculus
Superior colliculus
Divided into two areas: Tectum and tegmentum
Paresis (1)
Partial paralysis.
Paresis (2)
A syndrome of Inflammation of cerebral tissue cuasing mental and physical deterioration and caused by syphyllis.
Visual hallucination of terrifying faces
Inability to recognize familiar faces
Ganser’s syndrome
A factitious disorder characterized by the patient giving wrong or approximate answers, describing florid hallucinations, and sxs of conversion disorder. AKA nonsense syndrome.
Wernicke’s syndrome,
Aka wernicke’s aphasia, receptive aphasia, Fluent aphasia, impressive aphasia, sensory aphasia. Language production is intact but content is incorrect.
Broca’s aphasia
Aka expressive aphaisia, motor aphasia.
Gerstmann’s syndrome
Damage to parietal lobe. Agraphia/ dysgraphia, acalculia/ dyscalculia, finger agnosia, left right disorientation, aphasia.
Kluver-Bucy syndrome
Extensive bilateral damage to temporal lobes, amygdala, characterized by psychic blindness, prosopagnosia (check this), hypermetamorphosis (increased exploring of environment), hypersexuality, orality, decreased fear, affective blunting, bulimia,
Central vision processed in posterior occipital lobe. Peripheral in anterior occipital lobe.
Inability or unwillingness to recognize one’s functional impairments. Associated w damage to R parietal lobe.
Inability to recognize familiar objects
Inability to perform motor acts despite intact comprehension and motor function.
Frantal lobe
Damage here: apraxia, disinhibition,
Frontal lobe, R
Damage here: disinhibition, indifference, jocularity
Frontal lobe, L
Damage here: reduced speech, depression, apathy
Conduction aphasia
Caused by damage to nerve fibers between Broca’s and Wernicke’s areas. Leads to difficulty repeating what one has just heard.
Peripheralist theory of emotions
Early theory of emotions, we feel bc our bodies react
Emotions and thought occur nearly simultaneously.
5 stages:
Alpha waves
Theta waves, intermittent sleep spindles and K-complexes
Beta waves, also know as paradoxical sleep, since EEG pattern is characteristic of alertness
No effect on overall psychological functioning.
Parietal lobe
Contains primary somatosensory cortex.
Weber’s law
Explains relationship between physiological stimulation and its psychological effects. The Just noticeable difference is proportional to the magnitude of the original stimulus.
Identified inverted U relationship between arousal and performance.
Addison’s disease
Under-secretion of cortisol by adrenal glands. Fatigue, loss of appetite, decreased body weight, depression,
Cushing’s disease.
Over-secretion of cortisol by kidneys. Obesity, memory loss, mood swings, somatic delusions.
Hypothalamic neurons containing gonadotropic releasing hormine, projects to pituitary, which releases leutenizing hormone and follicular stimulating hormone. Circulating levels of these hormones control the release of sex hormone by gonads.
Stroop color word test
Test of frontal lobe damage, (especially left?). Names of colors are printed on cards in a different color ink, subject must name color, not read the word, as quickly as possible. Subj must inhibit reading the word. People with other disorders, e.g. ADHD, are able to do this.
Parkinsons disease
Associated w lack of dopamine and excess of ACH. Medical intervention can include increasing dopamine and/or decreasing ACH
Mental imaging
Structures involved include hippocampus, amygdala, other limbic studtures
Left-right agnosia
Correlated w damage to left angular gyrus of parietal lobe
Huntington’s Disease
Involves several structures, including basal ganglia. MRI at early stages can detect reduced volume in basal ganglia, especially caudate nucleus, even before sxs are present.
Study of the relationship between the magnitude of a physical stimulus and the internal experience of that magnitude.
Frontal lobe
Associated with decision making, attention, planning, working memory
Suprachiasmic Nucleus of hypothalamus
Regulates circadian rhythm. Gets info by pathway between it and light receptors in retina. Relays information to pineal gland, which releases melatonin.
OCD, tourette’s, Autisits d/os
2 areas show anomalies: frontal lobes, basal ganglia.
Anorexia and serotonin
High levels of serotonin linked to anxiety and starvation in anoriexia. High levels of serotonin cause anxiety, which anorectic manages by starving. This reduces tryptophan, which in turn reduces serotonin. This causes a sense of calm and control.
Bulimia and serotonin
Low levels of serotonin trigger binge eating, especially carbs, which increase serotonin and elevate mood.
Traumatic brain injury
Three types
Tissue Bruising:
Shearing: difficult to detect with x-ray, CT scan and MRI. PET scan more effective in detecting this type of injury.
Whole body spasm, SE of antipsychotics
