Abstract

A 58-year-old man recognized hoarseness and dysarthria followed by weakness of the left upper extremity. Examination five months later disclosed dementia which was manifested dominantly by changes in personality and behavior, but also by symptoms of amyotrophic lateral sclerosis. He became progressively weak, and his neck became rigid and extended for two months. He expired due to respiratory failure at the age of 60. At autopsy, the brain weighed 1120 g with atrophy of the temporal lobes. Microscopic examination revealed marked diminution of Betz cells with astrocytic proliferation in the motor cortex. There was a mild, localized spongy state in the upper layer in the frontal and temporal cortices. There were very few neurofibrillary changes and senile plaques, and no Pick's argentophilic bodies. Fibrillary gliosis was found in the white matter of the temporal lobes, external segment of the globus pallidus and the amygdaloid nucleus. The substantia nigra showed depletion of pigmented cells, free melanin pigment and reactive astrocytosis. A diminished number of motor neurons in the brain stem and spinal cord accompanied astrocytic gliosis, while the remaining cell contained many Bunina bodies. The pyramidal tracts showed mild d...Continue Reading

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.

Astrocytes & Amyloid

Astrocytes are thought to play a role in amyloid production and have been implicated in neurodegenerative diseases such as Alzheimer’s disease. Here is the latest research on the relationship between astrocytes and amyloid.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.

Amyloid Lateral Sclerosis

Amyotrophic Lateral Sclerosis (ALS) is a progressive nervous system disease associated with the death of neurons that control voluntary muscles. Discover the latest research on ALS here.
