Tasks we often perform in our everyday lives, such as reading or looking for a friend in the crowd, are seemingly straightforward but they actually require the orchestrated activity of several cognitive processes. Free-viewing visual search requires... Read More about Active search signatures in a free‐viewing task exploiting concurrent EEG and eye movements recordings.

Human vision supports prediction for moving stimuli. Here we take an individual differences approach to investigate whether there could be a common processing rate for motion-based visual prediction across diverse motion phenomena. Motion Induced Spa... Read More about Exploring the Common Mechanisms of Motion-Based Visual Prediction.

STDP Forms Associations between Memory Traces in Networks of Spiking Neurons (2019)
Journal Article

Memory traces and associations between them are fundamental for cognitive brain function. Neuron recordings suggest that distributed assemblies of neurons in the brain serve as memory traces for spatial information, real-world items, and concepts. Ho...

© 2018, The Author(s). Besides decades of research showing the role of the medial temporal lobe (MTL) in memory and the encoding of associations, the neural substrates underlying these functions remain unknown. We identified single neurons in the hum... Read More about Encoding of long-term associations through neural unitization in the human medial temporal lobe.

Parsing a mental program: fixation-related brain signatures of unitary operations and routines in natural visual search (2018)
Journal Article
Kamienkowski, J. E., Varatharajah, A., Sigman, M., & Ison, M. J. (2018). Parsing a mental program: fixation-related brain signatures of unitary operations and routines in natural visual search. NeuroImage, 183, 73-86. https://doi.org/10.1016/j.neuroimage.2018.08.010

Visual search involves a sequence or routine of unitary operations (i.e. fixations) embedded in a larger mental global program. The process can indeed be seen as a program based on a while loop (while the target is not found), a conditional construct...

Scene-selective coding by single neurons in the human parahippocampal cortex (2017)
Journal Article
Mormann, F., Kornblith, S., Cerf, M., Ison, M. J., Kraskov, A., Tran, M., …Fried, I. (2017). Scene-selective coding by single neurons in the human parahippocampal cortex. Proceedings of the National Academy of Sciences, 114(5), https://doi.org/10.1073/pnas.1608159113

Imaging, electrophysiological, and lesion studies have shown a relationship between the parahippocampal cortex (PHC) and the processing of spatial scenes. Our present knowledge of PHC, however, is restricted to the macroscopic properties and dynamics... Read More about Scene-selective coding by single neurons in the human parahippocampal cortex.

Long-term coding of personal and universal associations underlying the memory web in the human brain (2016)
Journal Article

Neurons in the medial temporal lobe (MTL), a critical area for declarative memory, have been shown to change their tuning in associative learning tasks. Yet, it is unclear how durable these neuronal representations are and if they outlast the executi...
