Lower white blood cell count associated with HIV infection was linked to decreased volume in the hippocampus and thalamus. Read More
Pyramidal cells in the CA2 region of the hippocampus are responsible for storing critical timing information. Read More
People with spinal cord injuries have the same brain activity during processing speed tasks as healthy older adults. The findings suggest the theory of accelerated cognitive aging following SCI is correct. Read More
Astrocytes, not microglia, are responsible for constantly eliminating unnecessary and excessive adult synaptic connections in response to brain activity. Read More
Study identifies a pathway involving astrocytes that help explain why some with multiple sclerosis experience seizures. Read More
Study reveals how the brain reacts when we encounter a person or object out of their normal context for the first time. Findings demonstrate how the memory system strives for efficiency and only encodes absolutely essential information. Read More
An imbalance in gut bacteria can cause the reduction of some metabolites, resulting in depression-like symptoms. The findings contribute to the growing body of evidence for the role the microbiome plays in brain function and mental health. Read More
Mouse study reveals how neurons reorganize following experiencing novel stimuli. The study reports a possible mechanism for memory consolidation and recall, shedding new light on the biological underpinnings for long-term memory. Read More
Two new studies advance understanding of how the brain encodes episodic memories. The findings have the potential to develop new avenues of treatment for memory loss associated with Alzheimer's disease and TBI. Read More
Free radicals help control cellular processes vital for neuroplasticity and neurogenesis in mice. Read More
Anxiety may accelerate the progression of mild cognitive impairment to Alzheimer's disease. Brain scans revealed patients who progressed from MCI to Alzheimer's disease had decreased volume in the hippocampus and entorhinal cortex. Read More
Older adults who experienced financial exploitation showed differences in brain activity in areas associated with social judgment and decision making. Additionally, those who are exploited financially tend to be physically frailer than their peers, with particular deficits in vision and hearing. Read More
