DOI: 10.1002/hbm.24469
Abstract: Gamma oscillations facilitate information processing by shaping the excitatory input/output of neuronal populations. Recent studies in humans and nonhuman primates have shown that strong excitatory drive to the visual cortex leads to suppression of induced… read more here.

DOI: 10.1002/hipo.23460
Abstract: Hippocampal neuronal oscillations reflect different cognitive processes and can therefore be used to dissect the role of hippocampal subfields in learning and memory. In particular, it has been suggested that encoding and retrieval is associated… read more here.

DOI: 10.1016/j.celrep.2017.10.123
Abstract: Neuronal oscillations in the rat hippocampus relate to both memory and locomotion, raising the question of how these cognitive and behavioral correlates interact to determine the oscillatory network state of this region. Here, rats freely… read more here.

DOI: 10.1016/j.conb.2018.07.009
Abstract: Gamma oscillations (∼25-100 Hz) are believed to play a role in cognition. Accordingly, aberrant gamma oscillations have been observed in several cognitive disorders, including Alzheimer's disease and Fragile X syndrome. Here, we review how recent results… read more here.

DOI: 10.1016/j.neuropharm.2017.04.009
Abstract: ABSTRACT In vivo, theta (4–7 Hz) and gamma (30–80 Hz) neuronal network oscillations are known to coexist and display phase‐amplitude coupling (PAC). However, in vitro, these oscillations have for many years been studied in isolation.… read more here.
