Epileptic and normal neurons in monkey neocortex: a quantitative study of degree of operant control

Brain Research
A R WylerK J Burchiel


The object of this study was to quantify and compare the degree of control monkeys may assert over firing patterns of normal and epileptic neurons. Thirty-seven epileptic and 70 normal neurons were studied in detail. The operant task was for the monkey to generate specified consecutive interspike intervals (ISI). The monkeys demonstrated far greater accuracy in controlling consecutive ISIs of normal neurons and were only able to control the intervals between bursts from epileptic neurons. The data implies that high frequency bursts of action potentials from epileptic neurons are all-or-nothing events initiated by synaptic mechanisms. In addition, some data are from a monkey with epilepsia partialis continua; in comparison to less active foci, this focus was comprised of a higher percentage of 'pacemaker' epileptic neurons.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults. Here is the latest research on separation anxiety.

KIF1A Associated Neurological Disorder

KIF1A associated neurological disorder (KAND) is a rare neurodegenerative condition caused by mutations in the KIF1A gene. KAND may present with a wide range and severity of symptoms including stiff or weak leg muscles, low muscle tone, a lack of muscle coordination and balance, and intellectual disability.
