What does cocaine do to the occipital lobe?
Cocaine affected 5-HT in the occipital cortex and behavioral activity in the same direction as visual stimulation, but in an amplified and prolonged way. In the temporal cortex cocaine also caused an increase in 5-HT.
How does cocaine affect parietal lobe?
Our results show reduced activation in the brain areas related to the attention system in cocaine-dependent men while performing a verbal working memory task. Chronic cocaine use may affect the attentional system in the right parietal lobe, making patients more prone to attentional deficits.
How does cocaine affect prefrontal cortex?
Growing evidence suggests that chronic drug exposure diminishes the function of the prefrontal cortex (PFC) – a component of the reward system – which is believed to cause cognitive and behavioral impairments that lead to the loss of inhibitory control over drug-seeking and drug-taking behaviors.
Does cocaine affect cognitive function?
Dr. Jedema and colleagues concluded that chronic cocaine use causes specific changes in brain structure that influence cognitive performance and can persist even after prolonged abstinence. Studies comparing people with and without cocaine use disorder detected similar patterns.
Can cocaine cause swelling on the brain?
By exposing endothelial cells to oxidative stress, cocaine can compromise the integrity of the BBB and lead to brain edema. Cocaine-induced neuroinflammation and production of inflammatory mediators can also affect the BBB and result in ionic edema, vasogenic edema, reversible cell swelling, or cytotoxic edema.
What affects the parietal lobe?
Damage to the Parietal Lobes. Damage to the parietal lobes may be the result of conditions such as a stroke, vascular disease, or a tumor. It could also have resulted from a traumatic brain injury or an infection.
What is Hyperfrontality?
n. a condition of reduced activation or inadequate functioning of the cortex of the frontal lobes of the brain. In theory, this is a factor in schizophrenia, but it is not well established either as a characteristic phenomenon or as a cause.
How does the parietal lobe get damaged?
As is the case with other traumatic brain injuries, damage to the parietal lobe most often occurs as a result of vehicle crashes, falls, and firearms. Taking steps to prevent these injuries could save you or a loved one a lifetime of the added stress that accompanies traumatic brain injuries.
Can hypofrontality be cured?
Treatment and management It is currently thought that a drug that could fully reverse the effects of hypofrontality would also effectively reverse the effects of certain neurological conditions; however, this has not been proven, and the drug has not yet been discovered.
