Terms

- Frontal Cortex
- Attention, executive functions
- Frontal Lobe Personality
- Apathy, inability to plan and focus attention, lack of drive; caused by lesions
- Autonomic Nervous System
- Comprised of Sympathetic Nervous System (fight or flight) and Parasympathetic Nervous System (deactivates)
- Acetylcholine
- Neurotransmitter controls muscle movements
- ARAS (Ascending Reticular Activating System)
- Behavioral arousal; provides stimulation to the entire cortex.
- Cerebellum
- Bodily movements, motor responses
- Medulla
- Breathing, heart rate, digestion
- Hippocampus
- Consolidation of memory
- Hypothalmus
- Regulating metabolism, body temperature, eating, sex, controls the endocrine system
- Thalmus
- Relays all sensory information to the cerebral cortex...except for olfactory.
- Split-Brain Patients
- Something shown in the left visual field, cannot name the object.
- Left Hemisphere
- Language
- Right Hemisphere
- Music
- Temporal Lobe
- Memory loss
- Estrogen replacement therapy (ERT)
- Reduces mood swings, reduces libido, reduces vaginal dryness, reduces risk of osteoporosis
- Akathesia
- Inability to sit still.
- Dystonia
- Sustained muscle contractions and spasms
- Dyskinesia
- Involuntary movements of head, trunk, and limbs.
- Parkinsonian Symptoms
- Muscle stiffness, shuffling gait, stooped posture
- Aphasia
- Inability to use or understand spoken, symbolic, or written language
- Phenothiazines/Neuroleptics
- Antipsychotic drugs associated with relief of positive psychotic symptoms, such as delusions and hallucinations.
- REM Sleep and Aging
- As one ages, both total sleep time and the proportion of REM sleep to non-REM sleep decreases.
- Corpus Callosum
- Connects the two hemispheres. Information perceived on the left side of the body gets projected to the right brain (and vice versa). The left hemisphere is responsible for most language functions. When the corpus callosum is severed, there is no communication between the two hemispheres.
- EMG Biofeedback
- More useful for treating tension headaches than migraines. For migraines, thermal biofeedback is more effective.
- Tricyclics
- imipramine, chomipramine, amitryptline
- SSRI
-
Prozac, Zoloft, and Paxil
Fluoxetine, setraline, and paroxetine - MAOIs
- Nardil and Parnate
- Long Term Potentiation
- Observed in hippocampal neurons and is thought to be responsible for structural changes in synapses that are related to the formation of memories.
- Hypothyroidism
- Under-secretion of thyroxin. Symptoms include slow metabolism, reduced appetite, weight gain, lowered heart rate and body temperature, decreased sex drive, depression, and deficits in cognition.
- What tests would you use to assess regional cerebral blood flow?
- PET and fMRI
- Inderal
- A beta-blocker that slows heart rate and other sympathetic nervous system activity. It is used to treat hypertension, migraines, and anxiety. Rapid withdrawal can result in headaches and palpitations.
- What can damage to the hippocampus cause?
- Impairment in the acquisition of new information.
- Suprachiasmatic Nucleus
- Located in the hypothalmus. It controls circadian rhythms.
- Left Cerebral Hemisphere
- Language-related functions and analytic tasks.
- Right Cerebral Hemisphere
- Recognition of non-verbal sounds, drawing, and recognition of emotional state.
- How does antipsychotic medication work?
- It reduces the activity of dopamine by blocking dopamine receptors in the brain. This can cause positive effects, but also side effects such as tardive dyskinesia and Parkinsonism.
- Tactile Agnosia
- Damage to the parietal lobe. Inability to recognize familiar objects.
- The most effective medication to treat OCD is...
- Clomipramine
- Benzodiazepines
- Valium, Xanax, Halcion, and Ativan. Major side effects are: drowsiness, impaired psychomotor abilities, and impaired short-term memory. It is not associated with impaired concept formation.
- Cannon and Bard Theory
- Emotions and thoughts occur more or less simultaneously.
- James and Lange Theory
- We first observe our behavior and then we make an attribution of that behavior in terms of some emotion.
- Wernicke's Aphasia
- The inability to understand spoken speech; receptive language.
- Apraxia
- Inability to execute purposeful movements.
- The Hippocampus is responsible for...
- Transfers information from short-term memory into long-term memory.
- Left Frontal Cortex controls...
- Verbal functions...expression of speech is on the left side.
- Broca's Area
- Responsible for expressive language. Located in the left frontal cortex.
- Symptoms of Hypothyroidism
- Mental slowing, delayed reflexes, and bradycardia
- Paresis
- Partial paralysis. Caused by damage to the pyramidal motor system, which consists of a pathway of neruons that descend from the brain and through the spinal cord. Weakness of movement.
- Wernicke's area is located...
- In the temporal lobe. Language comprehension.
- Conduction Aphasia
- A lesion of the pathway between Wernicke's and Broca's area. The person can speak clearly and understand language but cannot repeat what he or she has heard.
- Aphonia
- Inability to produce normal speech sounds.
- A MRI of a patient in the early stages of Huntington's disease would show...
- Reduced volume of the basal ganglia. Can be detected before a person exhibits symptoms.
- Hydrocephalus
- The flow of cerbrospinal fluid through the ventricles is blocked, producing abnormal pressue, which causes brain damage and mental retardation.
- Parkinson's Disease
- Due to a degeneration of dopamine-producing cells in the substantia nigra.
- Side Effects of Lithium
- Fine hand tremors, gastric distress, weight gain, fatigue, and mild confusion and disorientation.
- Functional Amnesia
- Memory problems that are due to psychological trauma, not injury to the brain. Characterized by loss of autobiographical information. Usually involves retrograde amnesia.
- Migraine Headaches
- Typically localized on one side of the head...unilaterally. Often accompanied by nausea and sensitivity to light.
- Hyperthyroidism
- Similar to panic disorder...anxiety, palpitations, sweating, and trembling.
