Prospective memory (PM), or memory to perform intended actions delayed to the future, plays a crucial role in daily tasks such as medication adherence. PM deficits commonly occur in normal aging and neurodegenerative diseases, highlighting the importance of understanding the underlying mechanisms to inform potential interventions. Brain regions active during PM tasks include the left dorsolateral prefrontal cortex (DLPFC) and inferior parietal cortex. PM tasks engage attentional networks, and changes in alpha frequency oscillations were observed during PM processing. We hypothesized that these

The precise relationship between cortical activity in the sensory areas and perception remains elusive. The perception of a given sensory stimulus can vary depending on the state of ongoing neural activity. Previous electroencephalogram (EEG) studies in humans have demonstrated distinctions in the power and phase angle of alpha oscillations (8-12 Hz) in the occipital region just before the stimulus onset between successfully detected (hits) and undetected (miss) trials (Busch et al., 2009; Dugué et al., 2011). Additionally, electrical microstimulation of V4 has shown to enhance performance in
