Object permanence allows infants to interact successfully with objects in the environment. What happens in the human infant brain when objects move in and out of sight? This study used high-density electroencephalography (hdEEG) to record induced oscillatory brain activities in 29 locomotor infants before, during, and after occlusion of a moving object traveling at different speeds. Temporal spectral evolution (TSE) showed that before and after the occlusion event, event-related synchronized (ERS) brain activity was observed, whereas event-related desynchronized (ERD) activity was detected when the car was hidden behind the occluder.

In locomotion, previous studies have identified a phenomenon known as cardiac locomotor synchronization (CLS), characterized by the phenomenon where heartbeats consistently occur at a specific time within the locomotor cycle. While the physiological significance of CLS is well recognized, its kinematic benefits remain uncertain. Therefore, this study aimed to elucidate the kinematic benefits of CLS under regular walking.

Control of voluntary limb movement is predominantly attributed to the contralateral motor cortex. However, increasing evidence suggests the involvement of ipsilateral cortical networks in this process, especially in motor tasks requiring bilateral coordination, such as locomotion. In this study, we combined a unilateral thoracic spinal cord injury (SCI) with a cortical neuroprosthetic approach to investigate the functional role of the ipsilateral motor cortex in rat movement through spared contralesional pathways.

Article Synopsis
- Freezing of gait (FOG) is a debilitating symptom of Parkinson's Disease and Progressive Supranuclear Palsy, leading to significant quality of life impairment, and its underlying mechanisms remain poorly understood.
- A study involving three patients with Progressive Supranuclear Palsy-progressive gait freezing (PSP-PGF) showed no deterioration in gait and balance after spinal cord stimulation (SCS) over 13 months, alongside notable changes in brain activity patterns.
- The findings indicate improved communication between brain and spinal circuits during SCS, suggesting potential advancements in treatments utilizing brain-spine interfaces for FOG patients.
Dopamine neurons that inform Drosophila olfactory memory have distinct, acute functions driving attraction and aversion.

The brain must guide immediate responses to beneficial and harmful stimuli while simultaneously writing memories for future reference. While both immediate actions and reinforcement learning are instructed by dopamine, how dopaminergic systems maintain coherence between these 2 reward functions is unknown. Through optogenetic activation experiments, we showed that the dopamine neurons that inform olfactory memory in Drosophila have a distinct, parallel function driving attraction and aversion (valence).
