Neurons that secrete oxytocin in the paraventricular nucleus in the hypothalamus are responsible for activating paternal instincts in new fathers, a mouse model study finds.
Daily release of glucocorticoids depends on coordination between the clock gene and activity rhythms of neurons within two parts of the hypothalamus.
Mouse mothers gathering their pups train female mice without pups to perform the same behavior. In virgin mice, observing the mother mouse take care of her pups stimulates oxytocin production, biologically shaping them for maternal behavior.
Researchers have identified a subset of neurons in a region of the hypothalamus that play a critical role in regulating feeding and appetite in mice.
A new study identifies the mechanisms behind neurotransmitters involved in circadian changes. The study has implications for chemical imbalances in the brain that can lead to mental health problems.
Researchers report a protein that mediates dysregulation of the HPA axis may induce postpartum disorder in some new moms.
Using optogenetics to manipulate the brains of opioid addicted mice, researchers discover a neural pathway that appears to be responsible for symptoms of withdrawal.
Researchers use optogenetics to tweak neural circuitry and enhance social memory in mice.
Researchers discover neural circuitry which promotes stress induced anxiety.
Researchers have shown stress on preadolesecent and adult male mice induced an epigenetic mark in their sperm which reprogrammed their offspring's HPA axis, a region the the brain which governs stress response.
