PointCell¶

class single_cell_parser.cell.PointCell(spikeTimes=None)¶

Cell without morphological or electrophysiological features.

Used as a presynaptic spike source for synapses. Stores spike times in neuron.h.Vector and numpy.array. Requires nrn.h.VecStim to trigger spikes at specified times.

Parameters:¶

spikeTimes (list) – List of precomputed spike times. Used to initialize release sites with precomputed release times from presynaptic spike times (see single_cell_parser.network.activate_functional_synapse()) Defaults to None.

Attributes:¶

spikeTimes¶

list of spike times. Default=None.

Type:¶

list

spikeVec¶

hoc Vector containing spike times

Type:¶

neuron.h.Vector

spikes¶

VecStim object to use as a spike source in NetCon objects (see https://www.neuron.yale.edu/neuron/static/py_doc/modelspec/programmatic/network/netcon.html). These are initialized from spikeTimes.

Type:¶

neuron.h.VecStim

playing¶

flag indicating whether the VecStim spike source is playing

Type:¶

bool

synapseList¶

list of synapses connected to this cell.

Type:¶

list

Methods:¶

is_active()	Check if the point cell is active.
play()	Activate point cell
append(spikeT, spike_source)	Append an additional spike time to the presynaptic cell.
compute_spike_train_times(interval, noise, start, stop, nSpikes, spike_source)	Compute a simple spike train for the presynaptic cell.
_next_interval()	Calculate the next spike interval $t$ for a simple spike train.
_add_synapse_pointer(synapse)	Add a reference to a synapse connected to this cell.
turn_off()	Turns off the spike source.
