Front Neural Circuits
. 2022 Jun;
16:893004.
PMID: 35769200
Complex tasks like hunting moving prey in an unpredictable environment require high levels of motor and sensory integration. An animal needs to detect and track suitable prey objects, measure their...

Bosse J, Svenson G, Bowers T, Bourges-Sevenier B, Ritzmann R
J Exp Biol
. 2022 May;
225(11).
PMID: 35502775
Most behavior needs to strike a balance between the competing needs to find food and protect an animal from predators. The factors that influence this balance and the resulting behavior...

Ritzmann R, Fox J
Curr Biol
. 2022 Jan;
32(2):R72-R74.
PMID: 35077690
A new study shows that a brain map in the monarch butterfly can be re-drawn during flight. Migrating butterflies integrate efferent and visual signals to create an adaptable compass in...

Pickard S, Bertsch D, Le Garrec Z, Ritzmann R, Quinn R, Szczecinski N
PLoS Comput Biol
. 2021 Dec;
17(12):e1009618.
PMID: 34928939
How we interact with our environment largely depends on both the external cues presented by our surroundings and the internal state from within. Internal states are the ever-changing physiological conditions...

Bertsch D, Martin J, Svenson G, Ritzmann R
J Exp Biol
. 2019 Jun;
222(Pt 11).
PMID: 31160429
At any given moment, behavior is controlled by a combination of external stimuli and an animal's internal state. As physiological conditions change, vastly different behaviors might result from the same...

Szczecinski N, Getsy A, Martin J, Ritzmann R, Quinn R
Arthropod Struct Dev
. 2017 Mar;
46(5):736-751.
PMID: 28302586
Insects use highly distributed nervous systems to process exteroception from head sensors, compare that information with state-based goals, and direct posture or locomotion toward those goals. To study how descending...

Varga A, Kathman N, Martin J, Guo P, Ritzmann R
Front Behav Neurosci
. 2017 Feb;
11:4.
PMID: 28174527
Cockroaches are scavengers that forage through dark, maze-like environments. Like other foraging animals, for instance rats, they must continually asses their situation to keep track of targets and negotiate barriers....

Varga A, Ritzmann R
Curr Biol
. 2016 Jul;
26(14):1816-28.
PMID: 27397888
Animals rely upon integrated sensory information for spatial navigation. A question of wide importance in navigation is how sensory cues get transformed into neural codes that represent the animal's orientation...

Martin J, Guo P, Mu L, Harley C, Ritzmann R
Curr Biol
. 2015 Nov;
25(21):2795-2803.
PMID: 26592340
To navigate in the world, an animal's brain must produce commands to move, change direction, and negotiate obstacles. In the insect brain, the central complex integrates multiple forms of sensory...

. 2015 Nov;
10(6):065005.
PMID: 26580957
Praying mantises hunt by standing on their meso- and metathoracic legs and using them to rotate and translate (together, 'pivot') their bodies toward prey. We have developed a neuromechanical software...
