Delta 9-tetrahydrocannabinol sensitization of the rat brain to direct cholinergic stimulation

G E Duncan, R Dagirmanjian


In an attempt to define the nature of the involvement of delta 9-tetrahydrocannabinol (THC) with central cholinergic neurotransmission, the effects of THC on direct cholinergic stimulation of the rat brain were investigated. THC, in doses of 3 mg/kg and 6 mg/kg, administered intraperitoneally (i.p.), potentiated the effects of carbachol injection into the lateral septal nucleus, as manifested by enhancement of the drinking response elicited by the septal carbachol injection and by potentiation of the tendency of this carbachol injection to induce abnormal motor responses. Although atropine (10 mg/kg, i.p.) completely blocked the carbachol induced drinking, the atropine did not completely block the drinking response when THC was given with carbachol. The results indicate an apparent sensitization, by THC, of a limbic cholinergic system.

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.

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.
