Findings could help researchers develop new treatments for stressed induced anxiety and other disorders.
Findings have implications for learning methods and memory consolidation.
Researchers implicate the locus coeruleus in storing memories of stressful events.
Trinity College Dublin researchers report controlled breathing, a key element of meditation, directly affects noradrenaline levels in the brain. The study suggests controlled breathing can enhance attention and improve overall brain health.
A new study sheds light on how the brain changes as a result of chronic stress. Selective noradrenaline release rewires connectivity patterns between different brain regions. Activity in the amygdala and networks that process sensory stimuli increased.
Adults with mild cognitive impairment (MCI), a precursor to Alzheimer's disease, have greater pupil dilation when taking cognitive tests than their cognitively normal peers. Task-evoked pupillary response may be a cost-effective, and low invasive screening test for those at genetic risk for Alzheimer's before the symptoms of the disease take hold.
