Distance-tuned neurons drive specialized path integration calculations in medial entorhinal cortex
During navigation, animals estimate their position using path integration and landmarks,
engaging many brain areas. Whether these areas follow specialized or universal cue …

Precisely timed theta oscillations are selectively required during the encoding phase of memory
Brain oscillations have been hypothesized to support cognitive function by coordinating
spike timing within and across brain regions, yet it is often not known when timing is either …

The direction of theta and alpha travelling waves modulates human memory processing
To support a range of behaviours, the brain must flexibly coordinate neural activity across
widespread brain regions. One potential mechanism for this coordination is a travelling …

Horizontal cortical connections shape intrinsic traveling waves into feature-selective motifs that regulate perceptual sensitivity
Intrinsic cortical activity forms traveling waves that modulate sensory-evoked responses and
perceptual sensitivity. These intrinsic traveling waves (iTWs) may arise from the coordination …

Correlated activity favors synergistic processing in local cortical networks in vitro at synaptically relevant timescales
Neural information processing is widely understood to depend on correlations in neuronal
activity. However, whether correlation is favorable or not is contentious. Here, we sought to …

Cross laminar traveling components of field potentials due to volume conduction of non-traveling neuronal activity in macaque sensory cortices
JJ Orczyk, A Barczak, J Costa-Faidella… - Journal of …, 2021 - Soc Neuroscience
Field potentials (FPs) reflect neuronal activities in the brain, and often exhibit traveling peaks
across recording sites. While traveling FPs are interpreted as propagation of neuronal …
