Cannabinoid type 2 receptors mediate a cell type-specific plasticity in the hippocampus

AV Stempel, A Stumpf, HY Zhang, T Özdoğan… - Neuron, 2016 - cell.com
Endocannabinoids (eCBs) exert major control over neuronal activity by activating

Spontaneous events outline the realm of possible sensory responses in neocortical populations

A Luczak, P Barthó, KD Harris - Neuron, 2009 - cell.com
Neocortical assemblies produce complex activity patterns both in response to sensory
stimuli and spontaneously without sensory input. To investigate the structure of these …

Spiking activity propagation in neuronal networks: reconciling different perspectives on neural coding

A Kumar, S Rotter, A Aertsen - Nature reviews neuroscience, 2010 - nature.com
The brain is a highly modular structure. To exploit modularity, it is necessary that spiking
activity can propagate from one module to another while preserving the information it …

Packet-based communication in the cortex

A Luczak, BL McNaughton, KD Harris - Nature Reviews Neuroscience, 2015 - nature.com
Cortical circuits work through the generation of coordinated, large-scale activity patterns. In
sensory systems, the onset of a discrete stimulus usually evokes a temporally organized …

[HTML][HTML] Spike-time-dependent plasticity and heterosynaptic competition organize networks to produce long scale-free sequences of neural activity

IR Fiete, W Senn, CZH Wang, RHR Hahnloser - Neuron, 2010 - cell.com
Sequential neural activity patterns are as ubiquitous as the outputs they drive, which include
motor gestures and sequential cognitive processes. Neural sequences are long, compared …

Unsupervised discovery of temporal sequences in high-dimensional datasets, with applications to neuroscience

EL Mackevicius, AH Bahle, AH Williams, S Gu… - Elife, 2019 - elifesciences.org
Identifying low-dimensional features that describe large-scale neural recordings is a major
challenge in neuroscience. Repeated temporal patterns (sequences) are thought to be a …

Regulation of spike timing in visual cortical circuits

P Tiesinga, JM Fellous, TJ Sejnowski - Nature reviews neuroscience, 2008 - nature.com
A train of action potentials (a spike train) can carry information in both the average firing rate
and the pattern of spikes in the train. But can such a spike-pattern code be supported by …

Natural stimuli evoke dynamic sequences of states in sensory cortical ensembles

LM Jones, A Fontanini, BF Sadacca, P Miller… - Proceedings of the …, 2007 - pnas.org
Although temporal coding is a frequent topic of neurophysiology research, trial-to-trial
variability in temporal codes is typically dismissed as noise and thought to play no role in …
