data






automated behavioral classification

classifications of
spontaneous behavior, assigned
by human investigators
and machine learning algorithms




neural circuit for handedness

neural circuit elements
(PB-FB-No projection neurons)
regulating behavioral diversity




phototactic choice histories

individual flies display
divergent light preferences
over time; color indicates
statistical significance




leg and fly motion

fictive motion of a fly
running on a ball
in the LegTracker
and the x- and y- coordinates
of its legs, over time




evolutionary phase space

predicted optimal
evolutionary strategies
underlying behavioral diversity,
varying across climate
and geography




behavioral ethograms

a visual representation
of the Markov transition rates
between various modes of
spontaneous fly behavior -
determined by the LegTracker




variation across species

the white clover weevil and
three Drosophila species
vary across strain and species
in how much phototactic
personality they have




effect of weather on behavior

predicted fly population dynamics
and phototactic behavior dynamics
as influenced by real world
weather conditions from 2008




exploration metric

schematic of a metric
to characterize spontaneous
exploration of a circular arena




GABAergic circuitry

GABAergic neurons in the
fan-shaped body and
ellipsoid body,
densely packed neural circuits
mediating locomotor decision-making




injury and gait

leg motion transition matrices
and gait schematics
before (top) and after (bottom)
amputation of a fly's fore leg




injury and exploration

exploratory paths,
segmented and registered,
before (blue) amputation of a leg,
immediately after (red), and
after a few recovery days (cyan)




leg proprioceptive organ

green fluorescent protein
expressed in the
femur chordotonal organ,
a sensory structure encoding
proprioceptive feedback





inventions






LegTracker

an instrument for
recording the position
of all 6 of a fly's legs,
in real time, at 80Hz




FlyVac

coordinates 32 modules
to autonomously measure
the light preference
of individual flies,
many times each




FlyVac Module

a behavioral T-maze
built into an circuit board,
uses infrared beams to
detect when a individual fly
chooses to go toward or away
from a light source




SlowPhotoBox

measures the resting
shade vs. light
light preference of
individual flies,
30 at a time




Y-maze array

measures locomotor handedness
and exploratory activity
of individual flies,
120 at a time





models






gait recover after injury

stages of exploratory
walking behavior following injury
and the genes required
to transition between these stages




fly life history

basic fly life history:
birth as an egg
metamorphosis
adulthood and egg-laying
various ways of dying




spatial decision-making circuit

a model of an azimuthal
decision-making circuit
in the central complex
of the fly brain




origin of phototactic personality

developmental timing
and genetic regulators
of phototactic personality




neurons regulating phototaxis

neuronal elements implicated
in the control of the
polarity, plasticity and variability
of phototactic responses
