Papez’s circuit
-Papez (1937) was among the first researchers to propose the existence of a neural circuit
-Play an important role in emotion, including certain areas of the cerebral cortex, the amygdala, and the hypothalamus.
General Adaptation Syndrome
Alarm reaction, resistance, exhaustion
maintains the body’s internal homeostasis
The hypothalamus also monitors the body’s internal states and initiates the responses needed to maintain homeostasis through its influence on the ANS and the pituitary and other endocrine glands
Symptoms of seizures
(a) an aura that signals the onset of the seizure (e.g., a feeling, odor, or noise); (b) a loss of consciousness; and (c) some type of abnormal movement.
Types of Seizures
Generalized seizures
Tonic-clonic (grand mal) seizures include a tonic stage in which the muscles contract and the body stiffens; a clonic stage that involves rhythmic shaking of the limbs; and postictal (postseizure) depression or confusion with amnesia for the ictal event
Absence (petit mal) seizures
-brief attacks involving a loss of consciousness without
-prominent motor symptoms.
During an absence seizure, the person often -exhibits a “blank stare” with frequent eye blinking. There is some evidence that the thalamus plays a role in the generation of absence seizures
Partial seizures
-simple partial seizures do not involve a loss of consciousness,
-complex partial seizures entail some alteration in consciousness.
-begin in one side of the brain and affect one side of the body initially,
Detect seizures
electroencephalograph (EEG), which is used to obtain evidence of abnormal electrical activity in the brain. In addition, CT, MRI, or other imaging technique may be used to determine if the seizures are related to a brain lesion or other abnormality.
Seizure (Epilepsy)
Excessive glutamate receptor activity
abnormal electrical activity in the brain
Stroke
o Sudden or gradual onset of neurological symptoms
o Disruption in blood supply to the brain
Temporal lobe damage
flow of information between the spinal cord and the brain
Huntington’s disease
gonadotropin-releasing hormone
a. Gonadotropin-releasing hormone causes the pituitary gland in the brain to make and secrete the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH)
b. Gonad gland secretes ovaries - estrogen, and progesterone; and testes – androgens (testosterone and androstenedione)
c. Estrogen and androgens are produced by both sexes.

Levodopa (L-Dopa)
central nervous system, conveying sensory information

reticular activating system
Lesions in the right (nondominant) hemisphere of the cerebral cortex

Wernicke-Korsakoff syndrome
excessive accumulation of cerebrospinal fluid (CSF) in the ventricles of the brain
