Scientists link growth hormone to anxiety and fear memory through specific neuron group

Growth hormone (GH) acts on many tissues throughout the body, helping build bones and muscles, among other functions. It is also a powerful anxiolytic. A study conducted by researchers at the University of São Paulo (USP) in Brazil has produced a deeper understanding of the role of GH in mitigating anxiety and, for the first time, identified the population of neurons responsible for modulating the influence of GH on the development of neuropsychiatric disorders involving anxiety, depression and post-traumatic stress. An article on the study is published in the Journal of…
