AI Article Synopsis

  • Locomotion in mammals is primarily regulated by intrinsic spinal cord networks known as central pattern generators (CPGs).
  • The functionality of these CPGs relies on the balance between inhibitory and excitatory neurons.
  • Recent research highlights the importance of excitatory synaptic transmission in these networks, particularly how specific excitatory neurons coordinate muscle activity and produce rhythmic movements.

Article Abstract

Locomotion in mammals is to a large degree controlled directly by intrinsic spinal networks, called central pattern generators (CPGs). The overall function of these networks is governed by interaction between inhibitory and excitatory neurons. In the present review, we will discuss recent findings addressing the role of excitatory synaptic transmission for network function including the role of specific excitatory neuronal populations in coordinating muscle activity and in generating rhythmic activity.

Excitatory neuron-prone prion propagation and excitatory neuronal loss in prion-infected mice.

Front Mol Neurosci

The accumulation of a disease-specific isoform of prion protein (PrP) and histopathological lesions, such as neuronal loss, are unevenly distributed in the brains of humans and animals affected with prion diseases. This distribution varies depending on the diseases and/or the combinations of prion strain and experimental animal. The brain region-dependent distribution of PrP and neuropathological lesions suggests a neuronal cell-type-dependent prion propagation and vulnerability to prion infection.

Excitatory synapses and the actin-rich dendritic spines on which they reside are indispensable for information processing and storage in the brain. In the adult hippocampus, excitatory synapses must balance plasticity and stability to support learning and memory. However, the mechanisms governing this balance remain poorly understood.

Targeted Recombination in Active Populations (TRAP) represents an effective and extensively applied technique that has earned significant utilization in neuroscience over the past decade, primarily for identifying and modulating functionally activated neuronal ensembles associated with diverse behaviors. As epilepsy is a neurological disorder characterized by pathological hyper-excitatory networks, TRAP has already been widely applied in epilepsy research. However, the deployment of TRAP in this field remains underexplored, and there is significant potential for further application and development in epilepsy-related investigations.

High-fat diet (HFD) -induced microglial activation contributes to hypothalamic inflammation and obesity, but the mechanisms linking microglia to structural changes remain unclear. This study explored the role of microglia in impairing hypothalamic synaptic plasticity in diet-induced obesity (DIO) mice and evaluated the therapeutic potential of semaglutide (Sema) and minocycline (MI). Six-week-old C57BL/6J mice were divided into low-fat diet (LFD) and HFD groups.

Despite the crucial role of synaptic connections and neural activity in the development and organization of cortical circuits, the mechanisms underlying the formation of functional synaptic connections in the developing human cerebral cortex remain unclear. We investigated the development of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR)-mediated synaptic transmission using human cortical organoids (hCOs) derived from induced pluripotent stem cells. Two-photon Ca⁺ imaging revealed an increase in the frequency and amplitude of spontaneous activity in hCOs on day 80 compared to day 50.
