Unique features of action potential initiation in cortical neurons
Neurons process and encode information by generating sequences of action potentials. For all spiking neurons, the encoding of single-neuron computations into sequences of spikes is biophysicallyExpand

Origin of Active States in Local Neocortical Networks during Slow Sleep Oscillation
Slow-wave sleep is characterized by spontaneous alternations of activity and silence in corticothalamic networks, but the causes of transition from silence to activity remain unknown. We investigatedExpand

Properties of Slow Oscillation during Slow-Wave Sleep and Anesthesia in Cats
Deep anesthesia is commonly used as a model of slow-wave sleep (SWS). Ketamine–xylazine anesthesia reproduces the main features of sleep slow oscillation: slow, large-amplitude waves in fieldExpand

Receptive field analysis and orientation selectivity of postsynaptic potentials of simple cells in cat visual cortex
Postsynaptic potentials (PSPs) were recorded from cat striate cortical cells by the whole-cell in vivo recording technique using patch-clamp electrodes. EPSPs and IPSPs evoked by flashing bars on theExpand

Precise Long-Range Synchronization of Activity and Silence in Neocortical Neurons during Slow-Wave Sleep
Slow-wave sleep is characterized by alternating periods of activity and silence in corticothalamic networks. Both activity and silence are stable network states, but the mechanisms of theirExpand

Detection of active and silent states in neocortical neurons from the field potential signal during slow-wave sleep.
Oscillations of the local field potentials (LFPs) or electroencephalogram (EEG) at frequencies below 1 Hz are a hallmark of the slow-wave sleep. However, the timing of the underlying cellular events,Expand

Precise long-range synchronization of activity and silence in neocortical neurons during slow-wave oscillations [corrected].
Slow-wave sleep is characterized by alternating periods of activity and silence in corticothalamic networks. Both activity and silence are stable network states, but the mechanisms of theirExpand

Synaptic transmission in the neocortex during reversible cooling
We studied the effects of reversible cooling on synaptic transmission in slices of rat visual cortex. Cooling had marked monotonic effects on the temporal properties of synaptic transmission. ItExpand

Ultrafast Population Encoding by Cortical Neurons
The processing speed of the brain depends on the ability of neurons to rapidly relay input changes. Previous theoretical and experimental studies of the timescale of population firing rate responsesExpand

Fast Computations in Cortical Ensembles Require Rapid Initiation of Action Potentials
The abilities of neuronal populations to encode rapidly varying stimuli and respond quickly to abrupt input changes are crucial for basic neuronal computations, such as coincidence detection,Expand
