A 2026 iScience study found that adults could learn a new auditory cue to visual depth after about 1 hour, but full perceptual integration did not appear reliably at the group level: only 31 of 63 participants, or 49%, gained precision when the novel cue was combined with familiar visual disparity.1 The sharp interpretation separates …
A 2026 rat study estimated that adult hippocampal neurogenesis added 670,000 dentate gyrus granule neurons from 2 to 18 months of age, but the total dentate gyrus population grew by only 385,000 cells because older developmentally born neurons were also being lost.1 The result makes adult neurogenesis look numerically larger than the usual “tiny trickle” …
A 2026 two-experiment study found no visual-working-memory benefit from parietal or occipital transcranial direct current stimulation, while distraction unexpectedly made the cardinal-over-oblique orientation advantage stronger than it was without distraction: the pooled distraction-by-angle interaction had BFinc = 1021.671.1 Research Highlights Distraction strengthened the bias: pooled data from 68 analyzed adults showed a strong distractor-by-angle interaction, …
A 2025 longitudinal analysis of 1,528 older Chinese Americans by Chen et al. in the Journal of Prevention of Alzheimer’s Disease says something more specific than “stress causes Alzheimer’s”: it isn’t the count of stressors that tracks memory decline — it’s a latent trait the authors call stress internalization, a bundle of high perceived stress, …
A 2026 PRISMA systematic review by Cavallo et al. in Cognitive, Affective, & Behavioral Neuroscience aggregates 43 neuroimaging studies of social cognition in adults with stroke or traumatic brain injury and finds the same handful of regions implicated again and again: the insula, cingulate cortex, middle frontal gyrus, and corpus callosum.1 Research Highlights Stroke/TBI social-cognition …
Cognitive impairment in first-episode schizophrenia (FES) is the symptom that does the most work blocking employment, relationships, and independent living — and the symptom current antipsychotics barely move. A 2026 RCT by Hu et al. in Psychological Medicine tested whether 20 sessions of low-frequency rTMS targeting the right orbitofrontal cortex (OFC) could improve cognition where …
A 2026 Molecular Psychiatry study found that RVI-AD, a structural-MRI score measuring how closely a person’s brain anatomy matches an Alzheimer’s disease pattern, predicted mild-cognitive-impairment conversion to dementia most strongly over the next 3 years: OR 2.16, 95% CI 1.81-2.57, p < 2e-16, AUC 0.70.1 Research Highlights Short-term conversion signal: in 965 ADNI participants with …
