Stress disrupts engram ensembles in lateral amygdala to generalize threat memory in mice.

Stress induces aversive memory overgeneralization, a hallmark of many psychiatric disorders. Memories are encoded by a sparse ensemble of neurons active during an event (an engram ensemble). We examined the molecular and circuit processes mediating stress-induced threat memory overgeneralization in mice.

Transient Stuttering as a Sole Presentation in a Patient With a Subcentimeter Left Frontal Cortical Ischemic Infarct.

Stuttering is a complex speech disorder that is associated with a variety of etiologies, including psychological factors, metabolic disorders, and structural abnormalities. While stuttering is typically not caused by stroke, it is important to include it in the diagnostic evaluation, especially in patients with a history of neurological conditions. Of the clinical presentations of stroke-induced stuttering, transient stuttering following stroke has seldom been documented, as most patients who develop a stutter following a stroke end up developing permanent speech deficits.

Isolated Self-Limited Right Oculomotor Nerve Palsy With Positive Asialo-GM1 Antibody After SARS-CoV-2 mRNA Vaccination.

mRNA vaccines have been a critical tool in combating the current coronavirus disease 2019 (COVID-19) pandemic and demonstrated a high safety profile. However, rare cases of isolated oculomotor nerve palsy following vaccination have been reported. These few reported cases can be divided into two groups based on symptom onset: immediate and delayed.

How We Found Consensus on Pediatric Decision-Making and Why It Matters.

This article describes the process engaged by 17 expert scholars in the development of a set of six consensus recommendations about the normative foundations of pediatric decision-making. The process began with a robust pre-reading assignment, followed by three days of in-person symposium discussions that resulted in a publication in Pediatrics entitled "Pediatric Decision-Making: Consensus Recommendations" (Salter et al. 2023).
