Disorder of speech, usually occurring secondary to stroke that causes a loss of control over the muscles of face and mouth. Pts. may drool, speak slowly, slur words, and display limited mouth and jaw movement.


Pure Alexia

A disorder of reading (AKA alexia without agraphia). Can spell and recognize words spelled to them but have great difficulty reading. Caused by damage to the connection between the visual cortex and the angular gyrus



A neurological disorder characterized by clumsy movements and poor coordination of musles.



Inability to move despite the urge and physical fitness necessary to do so. Can be very specific, ex. constructional apraxia, which only involves difficulty with drawing objects or constructing simple models.


Kluver-Bucy Sndrome

Neurological disorder thought to be caused by brain damage due to trauma or herpes encephalitis. Pts behave in sexually inappropriate ways, tend to put objects in mouth. May suffer from visual agnosia.


Ganser Syndrome

Factitious disorder where pts mimic behaviors they believe are characteristic of psychosis. May respond with nonsensical words when asked questions, engage in echolalia and echopraxia (rpting mvmts).


Angular Gyrsu

Located in the parietal lobe, just behind Wernickes area. Located on the margin of the occipital and temporal lobes. SErves to coordinate visual, spatial, and language-related information.


Causes of Gerstmann's Syndrome

Thought to be due to damage to the left parietal lobe in the area of angular gyrys


Gertsmann's Syndrome

Finger agnosia, right-left confusion, acalculia or dyscalculia, and agraphia. This is different from motor agraphia (find motor probe; poor muscle tone)


Occipital Lobe Damage

Results in visual-perceptual deficits, such as devpmt of scotomas; in addition visual hallucinations or illusions, (objects abnormally sized or colored), may become unable to read (alexia) or write (agraphia)


Parietal lobe damage

Causes abnormalities in body image and spatial perception; damage to the right parietal lobe can lead to contralateral neglect, construction apraxia, and anosognosia. Damage to the left results in Gertsmann's Syndrome.


Temporal Lobe damage

Causes auditory disturbances including auditory hallucinations, probs with visual perception, difficulty with language comprehension (Wernicke's aphasia), and impaired long term memory (anterograde amnesia)


Anterior Cingulate Cortex Damage

ACC allows for communication between cortex and limbic system. Also helps focus attention on tasks. ACC damage associated with inability to detect errors, difficulty resolving contradictory stimuli, emotional instability, poor attention, control, and loss of voluntary movement and speech.


Primary Motor Cortex

Executes movements. Damage here associated w/difficulties w/fine finger movement and a loss of speed and strength in the hands/limbs


Motor Association Cortex

Involved in the planning of movement. Damage here may cause difficulties coordinating the muscle movements required for speech


Broca's Area

Located in the left inferior frontal cortex and involved in word retrieval. Damage may cause Broca's aphasia (an inability to retrieve words)


Orbitofrontal Cortex

OFC - Associated with judgment, self-monitoring, and processing emotionally arousing stimuli. Damage here associated with poor or heightened response to threatening stimuli, poor decision making and judgment, and poor risk assessment (also disinhibited bx)


Dorsolateral prefrontal cortex

DLPFC - Associated with short term memory and top-down attentional control. Damage to this region associated with difficulties with concentration/attn., and poor recall of recently learned info


Prefrontal Cortex subdivisions

Dorsolateral prefrontal cortex, orbitofrontal cortex,, Broca's area, motor association cortex, and primary motor cortex


Damage to prefrontal cortex

Personality changes, and disturbances in planning, initiation, judgment,a nd goal-oriented behavior


Prefrontal cortex responsible for

Involved in executive function, planning, decision-making, attentional control, updating working memory


Caudate nucleus

Located within basal ganglia, may be involved in learning and memory and generating feelings of love; abnormalities in caudate nucleus linked to OCD


Cingulate Gyrus

Locate in the medial brain; receives input from the thalamus, somatosensory cortex, and other cortical areas; helps focus attn on tasks, and relay info between limbic system and higher cortical areas


Precocious puberty

A condition from premature activity of the hypothalamic-pituitary-gonadotropic axis. Leads to early sexual maturation


FSH and LH

In females, LH and FSH stimulate ovarian devpmt. In males, FSH essential for spermatogenesis and LH promotes testosterone synthesis



Regulate the gonads and the release of hormones necessary for sexual maturation; FSH and LH



Produced in stressful situations and stimulate release of hormones by the adrenal gland



Thyroid stimulating hormones that modulate metabolism in the thyroid gland


Anterior Pituitary Lobe

Controls the release of various hormones from endocrine organs


Disorders associated with the midbrain

Parkinson's - Degeneration of dopaminergic neurons in substantia nigra. Drug addiction - pleasurable effects of drug as well as addictive qualities are associated with functions of the VTA.
