New Key Mechanism of Epileptic Seizures Revealed
According to a new mathematical model of seizures, only the conductivity of the AMPA receptors in neurons in the temporal lobe significantly change, leading to stronger excitation and synaptic signals.... Read More...
GABA Cells Help Fight Alcoholism
Researchers have identified how alcohol influences dopaminergic and inhibitory neurons in the ventral tegmental area. The findings could help develop new treatments for alcohol dependence.... Read More...
New Genetic Clues to Frontotemporal Dementia
Study reports a mutation in a single gene that causes hereditary frontotemporal dementia makes it harder for neurons to communicate, leading to neurodegeneration.... Read More...
Schizophrenia Symptoms Alleviated: Mouse Study
Researchers have alleviated schizophrenia symptoms in mice by restoring the ErbB4 receptor.... Read More...
Researchers Solve Century Old Neuroscience Mystery
Researchers have solves a longstanding mystery relating to perineuronal nets, giving rise to potential new treatments for epilepsy. The study reports the nets modulate electrical impulses in the brain and seizures can occur if perineuronal networks are dissolved.... Read More...
Dopamine Drives Early Addiction to Heroin
Researchers have identified a significant role dopamine plays in the development of heroin addiction. The study reports dopamine appears to directly cause drug reinforcement and, when dopamine neurons are silenced, mice are less likely to self administer the drug.... Read More...
