I arrived at Tel-Aviv university in 2010, and I am affiliated with the Sagol School of Neuroscience and the school of Psychological Sciences. In my lab, we study how the brain performs online processing, focusing on the visual domain.
The cognitive structure responsible for these types of mental operations is called ‘Visual Working Memory’, an online buffer capable of holding a limited amount of information ready to be manipulated or accessed by high cognitive functions.
The importance of working memory capacity has been widely established in studies showing strong correlations between individual differences in working-memory capacity and a wide range of important capabilities such as attentional control, scholastic aptitudes and fluid intelligence.
Impairments in working-memory performance have been found in Alzheimer Disease, Schizophrenia, old age, and in children with ADHD. In order to investigate online processing and how it affects behavior, we use electrophysiology (EEG).
My lab has 2 EEG systems located in electrical shielded rooms.
We mostly rely on an event related potential termed the CDA (contralateral delay activity), which is a marker indicating the amount of visual working memory capacity at any given moment.
