Collateral Pathways from the Ventromedial Hypothalamus Mediate Defensive Behaviors
The ventromedial hypothalamus (VMH) was thought to be essential for coping with threat, although its circuit mechanism remains unclear. To investigate this, we optogenetically activated steroidogenic factor 1 (SF1)-expressing neurons in the dorsomedial and central parts of the VMH (VMHdm/c), and observed a range of context-dependent somatomotor and autonomic responses resembling animals' natura...
متن کاملSensing hypoglycemia: the ventromedial hypothalamus.
Hypoglycemia as a limiting factor in the treatment of diabetes mellitus with insulin was apparent even before the hormone was administered to patients. A passage in a biography of Banting notes: ‘The pace picked up as Banting and Best began adjusting extract . . . On December 2, 1921 . . . the injections threw the longevity dog, number 27, into repeated convulsions. . . . It finally died, kille...
متن کاملVentromedial Hypothalamus and the Generation of Aggression
Aggression is a costly behavior, sometimes with severe consequences including death. Yet aggression is prevalent across animal species ranging from insects to humans, demonstrating its essential role in the survival of individuals and groups. The question of how the brain decides when to generate this costly behavior has intrigued neuroscientists for over a century and has led to the identifica...
متن کاملGlucose Sensing Neurons in the Ventromedial Hypothalamus
Neurons whose activity is regulated by glucose are found in a number of brain regions. Glucose-excited (GE) neurons increase while glucose-inhibited (GI) neurons decrease their action potential frequency as interstitial brain glucose levels increase. We hypothesize that these neurons evolved to sense and respond to severe energy deficit (e.g., fasting) that threatens the brains glucose supply. ...
متن کاملAlimentary behavior in cats following lesions of the ventromedial hypothalamus.
The problem of the role of various parts of the hypothalamus in the regulation of food intake in animals is still not clear in spite of numerous studies concerning this subject. It is generally accepted that lesions in the ventromedial nucleus of the hypothalamus (VMH) produce hyper-phagia leading to obesity However, the extent and localization of lesions in particular papers are far from being...
