Animal models with constant, long-lasting motor deficits together with the right tests to assess behavioral abnormalities are needed to study the effectiveness of potential therapies to restore motor functions. In the current study, controlled cortical impact (CCI) was applied in rats to induce damage to the forelimb area of the motor cortex and the dorsal striatum. Motor behavior was assessed before and after CCI, using fine motor skill tests such as the adhesive removal test, the cylinder test, and the Montoya staircase test as well as the automated gait analysis system CatWalk XT over a 6 week period. CCI caused a variety of unilateral motor deficits, which were characterized in detail by using the selected fine motor skill tests. In striking contrast to previous studies on CCI in mice, neither forelimb impairments, nor general changes in gait, were detected with the CatWalk XT. These data suggest that the adhesive removal test, the cylinder test, and the Montoya staircase test are the methods of choice to detect long-term unilateral motor deficits in rats after CCI, whereas the use of automated gait analysis systems might not be suitable to measure these behavioral deviations.

This review aims to describe the neurologic post-COVID-19 conditions (PCC, also known as "long COVID"), a complex array of diagnoses that can occur following recovery from acute COVID-19. The review also includes clinical considerations for the recognition, diagnosis and management of neurologic manifestations of PCC. Cognitive impairment ("Brain Fog"), headaches, and neuropathies are specifically reviewed.

Loss of function in the subunits of the GTPase-activating protein (GAP) activity toward Rags-1 (GATOR1) complex, an amino-acid sensitive negative regulator of the mechanistic target of rapamycin complex 1 (mTORC1), is implicated in both genetic familial epilepsies and NDDs (Baldassari et al., 2018). Previous studies have found seizure phenotypes and increased activity resulting from conditional deletion of GATOR1 function from forebrain excitatory neurons (Yuskaitis et al.

Background And Aims: Preterm birth increases the risk of neurodevelopmental impairments, such as Cerebral Visual Impairment (CVI), which affects visual processing. Assessing visual functions in young children is challenging with traditional methods that often rely on verbal/motor responses. The aim of the study was to investigate the developmental trajectories of Visual Orienting Functions (VOF) in children born very preterm (<32 weeks gestational age) between 2 and 5 years corrected age (CA) using eye tracking.

Traumatic brain injury (TBI) is a life-threatening condition with high incidence and mortality rates. The current pharmacological interventions for TBI exhibit limited efficacy, underscoring the necessity to explore novel and effective therapeutic approaches to ameliorate its impact. Previous studies have indicated that transcranial pulsed current stimulation (tPCS) can improve neurofunctional deficits in patients by modulating brain neuroplasticity.

This review documents the importance of postoperative interventions that accelerate the functional recovery of the thoracic surgical patient. Enhanced recovery after surgery (ERAS) pathways aim to mitigate the harmful surgical stress response. Improvements to the entire patient pathway, by removing unnecessary care elements while introducing evidence-based interventions, have synergistic effects.
