The Volitional Control of Individual Motor Units Is Constrained within Low-Dimensional Neural Manifolds by Common Inputs

AI SummaryThe study investigates the dimensionality of control signals received by spinal motor neurons during ankle and knee joint torque control. Results show that individual motor units are not controlled independently but rather belong to synergistic groups constrained by common inputs. Specific muscle groups displayed differences in the ability to independently control motor units. This… Continue reading The Volitional Control of Individual Motor Units Is Constrained within Low-Dimensional Neural Manifolds by Common Inputs

RIM and RIM-Binding Protein Localize Synaptic CaV2 Channels to Differentially Regulate Transmission in Neuronal Circuits

AI SummaryThis study explores the role of Rab3-interacting molecule (RIM) and RIM-binding proteins in localizing voltage-gated Ca2+ channels (VGCCs) at synapses to regulate synaptic transmission in neuronal circuits. The research conducted in Caenorhabditis elegans hermaphrodites shows that mutations affecting RIM proteins result in altered neurotransmitter release, with different effects on cholinergic and GABAergic transmission. The… Continue reading RIM and RIM-Binding Protein Localize Synaptic CaV2 Channels to Differentially Regulate Transmission in Neuronal Circuits

Electrical Synapses Mediate Embryonic Hyperactivity in a Zebrafish Model of Fragile X Syndrome

AI SummaryThis research study explores the role of electrical synapses in mediating hyperactivity in a zebrafish model of Fragile X syndrome. The study found that Fragile X syndrome model mutant zebrafish exhibit hyperexcitability from the earliest stages of spontaneous behavior, have altered responses to blocking electrical gap junctions, and show increased expression of gap junction… Continue reading Electrical Synapses Mediate Embryonic Hyperactivity in a Zebrafish Model of Fragile X Syndrome

[Comment] Targeting C9orf72 in people with ALS

AI SummaryIn people with ALS, targeting C9orf72 could potentially offer a new avenue for treatment. ALS is a devastating disease that leads to paralysis and ultimately death, often due to respiratory failure. Cognitive and behavioral symptoms can also manifest in some individuals. By focusing on C9orf72, researchers aim to address the underlying mechanisms of ALS… Continue reading [Comment] Targeting C9orf72 in people with ALS

[Articles] Safety, tolerability, and pharmacokinetics of antisense oligonucleotide BIIB078 in adults with C9orf72-associated amyotrophic lateral sclerosis: a phase 1, randomised, double blinded, placebo-controlled, multiple ascending dose study

AI SummaryThis article discusses the safety, tolerability, and pharmacokinetics of the antisense oligonucleotide BIIB078 in adults with C9orf72-associated amyotrophic lateral sclerosis (ALS), based on a phase 1 study. The study did not show a reduction in neurofilament levels or benefit on clinical outcomes compared to the placebo group, leading to the discontinuation of BIIB078 clinical… Continue reading [Articles] Safety, tolerability, and pharmacokinetics of antisense oligonucleotide BIIB078 in adults with C9orf72-associated amyotrophic lateral sclerosis: a phase 1, randomised, double blinded, placebo-controlled, multiple ascending dose study

[In Context] Tofersen for SOD-1-associated amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) is a rare, progressive, and ultimately fatal neurodegenerative disease that causes loss of upper and lower motor neurons, leading to a progressive decrease in muscle mass, strength, and function of bulbar, respiratory and limb muscles, typically resulting in paralysis and eventually death from respiratory failure.
