Adaptive chunking improves effective working memory capacity in a prefrontal cortex and basal ganglia circuit

9 months 3 weeks ago
How and why is working memory (WM) capacity limited? Traditional cognitive accounts focus either on limitations on the number or items that can be stored (slots models), or loss of precision with increasing load (resource models). Here, we show that a neural network model of prefrontal cortex and basal ganglia can learn to reuse the same prefrontal populations to store multiple items, leading to resource-like constraints within a slot-like system, and inducing a trade-off between quantity and...

The Effect of Advancing Age and Intraocular Pressure Injury on Retinal Ganglion Cell Function and Synaptic Connectivity

9 months 3 weeks ago
Age and elevated intraocular pressure (IOP) are the two major risk factors for developing glaucoma, a leading cause of blindness worldwide that is characterized by the loss of retinal ganglion cells (RGCs). Although vision loss is irreversible over the long term, accumulating evidence points to short-term improvement of vision in glaucoma patients in response to certain interventions, suggesting that RGCs have the capacity to recover function. In the present study, we sought to investigate the...

Organizational Work, Well-Being, and Quality of Life at an Elderly Age: The Case of Cyprus

9 months 3 weeks ago
This study investigates the impact of postretirement organizational work on the well-being and overall quality of life of the elderly population in Cyprus. Specifically, it evaluates the multifaceted effects of continued employment after retirement, based on data collected through a survey administered to a representative sample of elderly Cypriots. The research findings, informed by prominent instruments in the field, demonstrate significant enhancements in autonomy, self-actualization, and...
