The role of astrocytic aquaporin-4 in synaptic plasticity and learning and memory
Aquaporin-4 (AQP4) is the predominant water channel expressed by astrocytes in the central nervous system. AQP4 is widely expressed throughout the brain, especially at the blood-brain barrier where AQP4 is highly polarized to astrocytic foot processes ...

Long-Term Depression of a Dopamine IPSC [PDF]
Two determinants of dopamine release from terminals in striatal and limbic structures are the pattern and rate of dopamine neuron firing in the ventral midbrain. This activity is regulated in part by somatodendritic release of dopamine and subsequent feedback inhibition through activation of D2receptors on dopamine neuron cell bodies and dendrites ...

Timing and Predictive Value of Clinical Conditions Preceding Multiple Sclerosis in the UK Biobank
ABSTRACT Objectives Multiple sclerosis (MS) patients often experience a higher incidence of clinical conditions before diagnosis, suggesting a prodromal phase. However, their predictive value and temporal trajectories remain underexplored. We investigated these aspects using the large UK Biobank's population‐based cohort, which provided clinical ...

Clinical Characteristics of Parkinsonism in HTLV‐1‐Associated Myelopathy
ABSTRACT Objective Human T‐lymphotropic virus type 1 (HTLV‐1)‐associated myelopathy/tropical spastic paraparesis (HAM/TSP) is the classic neurological manifestation of HTLV‐1 infection; however, this virus has also been associated with other neurological disorders. Concurrent parkinsonism is relatively rare and presents diagnostic challenges.

Multiple forms of metaplasticity at a single hippocampal synapse during late postnatal development
Metaplasticity refers to adjustment in the requirements for induction of synaptic plasticity based on the prior history of activity. Numerous forms of developmental metaplasticity are observed at Schaffer collateral synapses in the rat hippocampus at the

ABSTRACT Objective Spinal muscular atrophy (SMA) significantly impacts motor function. This study aimed to assess the persistent burden and unmet needs among currently treated patients with SMA and their caregivers. Methods Two complementary web‐based surveys were distributed in August 2024 among patients with SMA and their caregivers.

Climbing fiber signaling and cerebellar gain control
The physiology of climbing fiber signals in cerebellar Purkinje cells has been studied since the early days of electrophysiology. Both the climbing fiber-evoked complex spike and the role of climbing fiber activity in the induction of long-term ...

Identification of Dementia With Lewy Bodies by Skin Biopsy in Recent‐Onset Cognitive Impairment
ABSTRACT Immunofluorescence for phosphorylated alpha‐synuclein in skin biopsy samples is an emerging biomarker in synucleinopathies comprising Dementia with Lewy bodies. In this pilot study, 19 patients with recent‐onset (≤ 18 months) cognitive impairment underwent skin biopsy at baseline, with follow‐up clinical re‐evaluation.
