The memory part of the brain may also hold clues for anxiety and depression

The hippocampus is an area of the brain commonly linked with memory and dementia. But new U of T Scarborough research finds that it may also yield important clues about a range of mental health illnesses including addiction, anxiety and depression. The research, authored by a team of neuroscientists, found that a specific part of the hippocampus could play an important role in emotional regulation, a finding that calls into question our understanding of how…

Area of brain linked to bipolar disorder pinpointed

A volume decrease in specific parts of the brain’s hippocampus — long identified as a hub of mood and memory processing — was linked to bipolar disorder in a study led by researchers at The University of Texas Health Science Center at Houston (UTHealth). The research was published today in Molecular Psychiatry, part of the Nature Publishing Group. “Our study is one of the first to locate possible damage of bipolar disorder in specific subfields within…

How Might New Neurons Buffer Against Stress?

Over the past decade or so, evidence has emerged suggesting that the birth of new neurons in the adult brain’s memory hub, or hippocampus, may play a key role the action of antidepressants, resilience to stress, the benefits of exercise and enriched environments and preventing memory loss. But understanding how it might work has remained elusive. Heather Cameron,Ph.D., chief of the NIMH intramural Unit on Neuroplasticity, discussed findings of ongoing studies on the function of adult neurogenesis in the hippocampus at a…
