Rab3A, a possible marker of cortical granules, participates in cortical granule exocytosis in mouse eggs
(Elsevier Inc, 2016-09)
Fusion of cortical granules with the oocyte plasma membrane is the most significant event to prevent polyspermy. This particular exocytosis, also known as cortical reaction, is regulated by calcium and its molecular mechanism ...
Cortical activity and gait parameter characteristics in people with multiple sclerosis during unobstructed gait and obstacle avoidance
(2021-05-01)
Background: People with Multiple Sclerosis (PwMS) present higher cortical activity during walking. However, the cortical activity during gait while avoiding an obstacle is still not clear. Objective: To investigate cortical ...
Complex, multifocal, individual-specific attention-related cortical functional circuits

Monitoring multiple cortical regions during walking in young and older adults: Dual-task response and comparison challenges
(2019-01-01)
Performance of several tasks simultaneously (dual-tasks) is common in everyday walking. Studies indicate that dual-task walking performance declines with age together with cognitive function, but neural mechanisms underpinning ...
GDNF/GFRα1 Complex Abrogates Self-Renewing Activity of Cortical Neural Precursors Inducing Their Differentiation
(Cell Press, 2018-03)
The balance between factors leading to proliferation and differentiation of cortical neural precursors (CNPs) determines the correct cortical development. In this work, we show that GDNF and its receptor GFRα1 are expressed ...
Non-homogeneous spatial configuration of vibrissae cortical representation in layer IV of the barrel somatosensory cortex

Cortical activity during walking and balance tasks in older adults and in people with Parkinson's disease: A structured review
(2018-07-01)
An emerging body of literature has examined cortical activity during walking and balance tasks in older adults and in people with Parkinson's disease, specifically using functional near infrared spectroscopy (fNIRS) or ...
Prefrontal Cortical Activity During Preferred and Fast Walking in Young and Older Adults: An fNIRS Study
(2021-10-01)
Age-related changes may affect the performance during fast walking speed. Although, several studies have been focused on the contribution of the prefrontal cortex (PFC) during challenging walking tasks, the neural mechanism ...
