INTRODUCTION. 1. Animals with bilateral symmetry usually have: - an anterior part dominated by sensory processing and - a posterior part dedicated mostly to (loco)motor functions. There is also a sequential rostrocaudal representation of these processes in the brain. 2. The design of robots and machines has received inspiration from the general properties of this architecture. 3. The left-right preferences (e.g. handedness) of the fire ant Solenopsis Invicta has been studied for the jaws and legs (Cassill 2007, 2009). 4. We have proposed that there are AnteriorPosterior Processes (APP) that organize the left-right electrophysiological signaling of the brain (in humans, by multiplexing, Gomez 1986, BS-Thesis; Gomez and Lopera 1997 DOI: 10.1109/ICNN.1997.611697 ) as well as the turning behavior and spatial preferences during locomotion (in ants, Gomez, 2007, PhD-thesis, UTSA; Gomez and Renthal, SfN-abstract 2007). 5. A bilateral architecture defines a coordinate system and left/right spaces outside of the body where asymmetries can be projected. 6. Asymmetry of antennal grooming in cockroach has been reported (Zhukovskaya 2016). In this work we continue to explore theoretically and computationally how Left-Right Processes (LRP) are coordinated with APP at different levels.

METHODS. Mathematical and computational tools. Video-recordings in ants and cockroaches during spontaneous behaviors (locomotion, turning, grooming) in the field and in the laboratory. CONCLUSIONS. 1. Differences in phase and intensity of LRP can cause asymmetry in behavioral activity at the individual and at the ecological level (i.e. invasion, propagation and distribution patterns of colonies and insects). 2. In neural models of insect turning and navigation, angular and linear information present a trade-off (*) that can be spatially coded by LRP and APP. 3. Analyzing locomotion in insects is a powerful method to introduce complex analog processes in the classroom like random walks, directed walks (idiothetic and allothetic) and levy walks. 4. Subroutines of random walks and APP vs. LFP coordination can be recurrently called at different levels, from molecular to ecological levels (e.g. see GomezMolina, Corredor, Restrepo, Ricoy 2015 Computer Simulation for ions under electric and magnetic fields.

This work (an initiative of the International Group of Neuroscience, IGN) is intended to involve universities at TX (University of Texas at San Antonio UTSA), FL (University of South Florida USF), NM (Northern New Mexico Collegue NNMC), CA (University of California UC) and Colombia (University of Antioquia UdeA).
Abbreviations and Definitions
AL: Antennal lobes. It is a neuropil which receives information from olfactory sensory neurons on the antenna. The network structure of the AL is very similar to the olfactory bulb in vertebrates and it performs similar computations. The neurons of the AL project to the MB. APP: Anterior-Posterior Processes. CB: Central body. It is an structure located in the brain midline. It is composed of five modules: the protocerebral bridge (PB), fanshaped body (FB), ellipsoid body (EB), noduli (N) and lateral accessory lobes (LAL). These modules play roles in organizing motor activity, orientation, left-right computations and visual pattern memory. CC: Central complex. In cockroaches CC integrates visual and antennal information and it is linked to turning behaviors (Guo P and Ritzmann RE 2013) and therefore to processing of left-right information. CC might be associated with orientation and navigation. Submodules (columnar organizations of cells) in the PB of the CC have been described. The terms CC and CB do not always correspond to the same structures for some authors and species. Some neurons in CC respond to locomotion states. LRP: Left-Right Processes.
MB: The Mushroom bodies, composed of Kenyon cells, are essential for learning and memory. These neurons represent olfactory information and they might have high frequency synchronization (in some insects). They send the information at specific phases of these frequencies. Learning is facilitated by dopamine, a neurotransmissor that play a role in reward and addiction in vertebrates. PB: Protocerebral bridge. Some columns seems to be activated with the global activation states of the insect.
