   Astrocyte networks may play a larger role in attention than previously thought.

   Source: Cell Reports · Verma et al., 2026

   A new study using in-vivo two-photon imaging in mice suggests astrocyte calcium waves modulate attention circuits in ways once attributed to neurons alone. Small sample, mouse model — but a striking hint that the support cells are doing more than support.

1. Emotion Regulation30 Jun 2026

   Naming an emotion precisely reduces its physiological intensity within 90 seconds.

   Replicated across two labs: participants who labeled their emotional state with granular vocabulary showed measurably lower skin-conductance response inside a 90-second window compared to controls using broad category labels. Effect size modest but consistent.

1. Polyvagal22 May 2026

   Long-form review reopens debate on the anatomical claims of Polyvagal Theory.

   Source: Frontiers in Human Neuroscience · Grossman, 2026

   A widely-shared 42-page review argues that key anatomical predictions of Polyvagal Theory have not been supported by post-2020 vagal-fiber studies, while conceding the clinical framework retains value. The community response has been unusually engaged.

1. Interoception14 Apr 2026

   Higher interoceptive accuracy correlates with improved emotional recovery after conflict.

   Source: Biological Psychology · Khalsa et al., 2026

   In a preregistered study of 214 couples, individuals with higher interoceptive accuracy (heartbeat-detection task) recovered to baseline heart-rate variability significantly faster following induced conflict. Suggests interoception may be a modifiable buffer for relational stress.

1. Memory8 Mar 2026

   Sleep spindles during the first REM cycle predict next-day emotional-memory retention.

   Source: Nature Neuroscience · Walker Lab, 2026

   A large-N (n=402) polysomnography study shows spindle density in the first REM window uniquely predicts recall of emotionally-charged events 24 hours later — above and beyond total sleep duration. May reshape sleep-hygiene recommendations for trauma-adjacent populations.

   Allostatic-load biomarkers respond to a 12-week co-regulation intervention.

   Small (n=68) RCT reports significant reductions in composite allostatic-load score after a 12-week co-regulation program (weekly dyadic breath practice + polyvagal-informed group). Effects retained at 6-month follow-up. Independent replication pending.

1. Reconsolidation25 Jan 2026

   Beta-blocker propranolol continues to show promise for softening traumatic memories.

   Source: JAMA Psychiatry · Brunet Lab, 2026

   A pre-registered phase-II trial of propranolol-augmented memory reactivation shows sustained reductions in PTSD symptom clusters at 12 months. Not a cure — but the mechanism (memory reconsolidation) is finally holding up under scrutiny.

   Adult hippocampal neurogenesis: the tide keeps turning.

   Source: Science · Boldrini et al., 2025

   The long-running debate over whether adult humans grow new hippocampal neurons swings again toward yes. Fresh post-mortem tissue methods identify markers of neurogenesis at 79 years of age. The field is not settled — but the older "only in childhood" view looks increasingly unlikely.

1. Somatic Practice4 Nov 2025

   Slow-exhale breathing shifts HRV within a single 5-minute session — but the effect fades.

   Source: Applied Psychophysiology and Biofeedback · Steffen, 2025

   A tightly-controlled crossover study confirms that resonance-frequency breathing (~6 breaths per minute) reliably elevates HRV — but only during, and briefly after, the practice. Sustained gains require weeks of repetition, not one-off sessions.
