PyOpenWorm.neuron module

class PyOpenWorm.neuron.ConnectionProperty(**kwargs)[source]

Bases: PyOpenWorm.pProperty.Property

A representation of the connection between neurons. Either a gap junction or a chemical synapse

TODO: Add neurotransmitter type. TODO: Add connection strength

get(pre_post_or_either='pre', **kwargs)[source]

Get a list of connections associated with the owning neuron.

Parameters:
pre_post_or_either: str

What kind of connection to look for. ‘pre’: Owner is the source of the connection ‘post’: Owner is the destination of the connection ‘either’: Owner is either the source or destination of the connection

Returns:
list of Connection
set(conn, **kwargs)[source]

Add a connection associated with the owner Neuron

Parameters:
conn : PyOpenWorm.connection.Connection

connection associated with the owner neuron

Returns:
A PyOpenWorm.neuron.Connection
class PyOpenWorm.neuron.Neighbor(**kwargs)[source]

Bases: PyOpenWorm.pProperty.Property

get(**kwargs)[source]

Get a list of neighboring neurons.

Parameters:
See parameters for PyOpenWorm.connection.Connection
Returns:
list of Neuron
set(other, **kwargs)[source]

Set the value of this property

Derived classes must override.

class PyOpenWorm.neuron.Neuron(name=False, **kwargs)[source]

Bases: PyOpenWorm.cell.Cell

A neuron.

See what neurons express some neuropeptide

Example:

# Grabs the representation of the neuronal network
>>> net = P.Worm().get_neuron_network()

# Grab a specific neuron
>>> aval = net.aneuron('AVAL')

>>> aval.type()
set([u'interneuron'])

#show how many connections go out of AVAL
>>> aval.connection.count('pre')
77

>>> aval.name()
u'AVAL'

#list all known receptors
>>> sorted(aval.receptors())
[u'GGR-3', u'GLR-1', u'GLR-2', u'GLR-4', u'GLR-5', u'NMR-1', u'NMR-2', u'UNC-8']

#show how many chemical synapses go in and out of AVAL
>>> aval.Syn_degree()
90
Parameters:
name : string

The name of the neuron.

Attributes:
neighbor : Property

Get neurons connected to this neuron if called with no arguments, or with arguments, state that neuronName is a neighbor of this Neuron

connection : Property

Get a set of Connection objects describing chemical synapses or gap junctions between this neuron and others

GJ_degree()[source]

Returns:total number of incoming and outgoing gap junctions
Return type:int
Syn_degree()[source]

Get the degree of this neuron for chemical synapse edges only

Returns:total number of incoming and outgoing chemical synapses
Return type:int
get_incidents(type=0)[source]
