TL;DR: A network model in Communications Physics (2026) found that Hebbian learning, the familiar “fire together, wire together” rule, trapped activity in old routes, while anti-Hebbian weakening helped activity reach new areas. Key Findings Positive reinforcement trapped activity: when successful activation made the same link more likely to be used again, activity tended to circle …
TL;DR: A 2026 Nature Communications study found that HCN1, an ion channel that helps neurons start rhythmic electrical firing, was fast enough to act as the trigger for neuronal pacemaker depolarization, while HCN2 and HCN4 mainly appeared too slow to drive each action-potential cycle. Key Findings HCN1 was the fast channel: In slow action-potential clamp …
TL;DR: A 2026 mouse study in Nature Neuroscience found that glucose signaling through ATP-citrate lyase (ACLY), an enzyme that links sugar metabolism to gene regulation, helped oligodendrocyte progenitor cells multiply before they matured into myelin-forming cells. Key Findings Glucose mapped onto cell state: Developing mouse-brain regions with higher glucose had more proliferating oligodendrocyte progenitor cells, …
TL;DR: A 2026 retrospective case series study in European Journal of Psychotraumatology found that trauma flashbacks during esketamine nasal spray sessions were distressing but usually time-limited in 22 patients with treatment-resistant depression and PTSD; when treatment continued, depression response was 45.5% and PTSD improvement was 45.5%. Key Findings 22-patient case series: Researchers reviewed adults with …
TL;DR: A 2026 review in Neuropsychiatric Disease and Treatment argued that electroacupuncture (EA), acupuncture delivered with small electrical stimulation, has depression-related mechanism evidence, but clinical trials need biomarker-guided patient groups, standardized stimulation dose, and objective outcomes before EA can be treated as precision depression care. Key Findings Clinical evidence remains uneven: some randomized trials and …
TL;DR: A 2026 study in Health Science Reports found that metoclopramide and several antipsychotics were strongly overrepresented in FDA adverse-event reports for drug-induced dystonia, with many reported cases appearing within the first month after drug initiation. Key Findings 28,938 dystonia reports: Researchers analyzed FDA Adverse Event Reporting System records from the first quarter of 2004 …
TL;DR: A 2026 study in Consciousness and Cognition found that waking mind wandering and nighttime dreaming had nearly the same density of bizarre elements, even though dreams were more likely to be rated as bizarre whole reports. Key Findings 379 experience reports: Researchers analyzed daily audio descriptions of one dream and one waking mind-wandering episode …
TL;DR: A 2026 study in Epigenetics found that DNA methylation clocks, which estimate biological aging from chemical marks on DNA, gave substantially older age estimates in saliva than in two blood-derived samples from 91 early-to-mid-adult participants. Key Findings The sample included 91 adults: Researchers analyzed participants from a twin and sibling study with a mean …
TL;DR: A 2026 preprint in medRxiv using ABCD Study data found that childhood poverty strengthened the link between early-life adversity and later behavioral problems, while inhibitory-control brain and temperament profiles separated higher- and lower-risk patterns within poverty-exposed youth. Key Findings 10,112 youth were analyzed: Researchers used the Adolescent Brain Cognitive Development Study to link baseline …
TL;DR: A 2026 Nature Communications study followed 100 Swedish participants from age 4 to 24 and found that more than half of detectable blood proteins changed with age, with sex-related protein differences becoming much larger by adolescence and early adulthood. Key Findings Four repeated blood draws: Researchers measured plasma proteins at ages 4, 8, 16, …
