Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.Abstract Neuromodulatory subcortical systems (NSSs) are uniquely susceptible to dementia‐related pathology, leading to frequent molecular and behavioral impairments associated with altered function of these nuclei. Some of these systems display clear sex‐specific cytoarchitecture and signaling leading to distinct physiology and behavioral outputs in ...

Engram Synapses and Synapse Dynamics in Memory Processing
Journal of Neurochemistry, Volume 170, Issue 3, March 2026.Learning‐induced neuronal activity dynamically rewires synapses, altering their formation and elimination rates in task‐related regions. In vivo two‐photon imaging has revealed that activity‐driven presynaptic, postsynaptic, and astrocytic mechanisms regulate synaptogenesis and axonal bouton engulfment.

Annals of Clinical and Translational Neurology, Volume 13, Issue 2, Page 405-412, February 2026.ABSTRACT Mutations in myelin regulatory factor (MYRF) are linked to demyelinating disorders. We report a 38‐year‐old male who developed acute symmetric leukoencephalopathy mimicking a stroke following an influenza A virus infection. While clinical symptoms markedly improved with corticosteroids, MRI revealed persistent white matter lesions, contrasting

Overtraining Strengthens the Visual Discrimination Memory Trace Outside the Hippocampus in Male Rats
Frontiers in Behavioral Neuroscience, 2021 The hippocampus (HPC) may compete with other memory systems when establishing a representation, a process termed overshadowing. However, this overshadowing may be mitigated by repeated learning episodes, making a memory resistant to post-training ...

Air pollution and its multifaceted effects on insect pollinators: A review
Ecological Entomology, Volume 51, Issue 1, Page 1-17, February 2026.Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.

Retrograde Amnesia in Parkinson’s Disease [PDF]
Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1984 ABSTRACT:Retrograde amnesia was assessed in demented and non-demented Parkinson’s patients using a test of remote memory spanning the years from 1920-1979. Results indicated that the demented patients 1) scored significantly below normal controls and 2) had equal impairment for all time periods.
