looking for complexity in quantitative semiology of frontal and temporal lobe seizures using Neuroethology and graph theory
Epilepsy & Behavior, 2014Co-Authors: Poliana Bertti, Julian Tejada, Ana Paula P Martins, Maria Luiza Cleto Dalcol, Vera C Terra, Jose Antonio Cortes De Oliveira, Tonicarlo Rodrigues Velasco, Americo Ceiki Sakamoto, Norberto GarciacairascoAbstract:Epileptic syndromes and seizures are the expression of complex brain systems. Because no analysis of complexity has been applied to epileptic seizure semiology, our goal was to apply Neuroethology and graph analysis to the study of the complexity of behavioral manifestations of epileptic seizures in human frontal lobe epilepsy (FLE) and temporal lobe epilepsy (TLE). We analyzed the video recordings of 120 seizures of 18 patients with FLE and 28 seizures of 28 patients with TLE. All patients were seizure-free >1 year after surgery (Engel Class I). All patients' behavioral sequences were analyzed by means of a glossary containing all behaviors and analyzed for Neuroethology (Ethomatic software). The same series were used for graph analysis (CYTOSCAPE). Behaviors, displayed as nodes, were connected by edges to other nodes according to their temporal sequence of appearance. Using Neuroethology analysis, we confirmed data in the literature such as in FLE: brief/frequent seizures, complex motor behaviors, head and eye version, unilateral/bilateral tonic posturing, speech arrest, vocalization, and rapid postictal recovery and in the case of TLE: presence of epigastric aura, lateralized dystonias, impairment of consciousness/speech during ictal and postictal periods, and development of secondary generalization. Using graph analysis metrics of FLE and TLE confirmed data from flowcharts. However, because of the algorithms we used, they highlighted more powerfully the connectivity and complex associations among behaviors in a quite selective manner, depending on the origin of the seizures. The algorithms we used are commonly employed to track brain connectivity from EEG and MRI sources, which makes our study very promising for future studies of complexity in this field.

Neuroethology application for the study of human temporal lobe epilepsy from basic to applied sciences
Epilepsy & Behavior, 2006Co-Authors: Maria Luiza Cleto Dalcol, Jose Antonio Cortes De Oliveira, Tonicarlo Rodrigues Velasco, Americo Ceiki Sakamoto, Vera Cristina Terrabustamante, Norberto GarciacairascoAbstract:The aim of this investigation was to apply Neuroethology to the study of human temporal lobe epilepsy (TLE). For this purpose, 42 seizures in 7 patients recorded during video/EEG monitoring (1997-1998) were analyzed by means of a behavioral glossary containing all behaviors. Video recordings were reobserved, and all patients' behaviors were annotated second-by-second. Data were analyzed using Ethomatic software and displayed as flowcharts including frequency, mean duration, and sequential statistic interaction of behavioral items (chi2 > or = 10.827, P<0.001). Flowcharts of (1) a group of seizures from a single patient, (2) the sum of four seizures per patient of two patients with right and five patients with left TLE, and (3) the comparison of left versus right TLE are shown. Well-established data in the literature were confirmed, such as aura (especially epigastric), contralateral lateralization value of dystonia and version, consciousness and language alterations in ictal and postictal periods, mostly with respect to dominant hemisphere involvement, among others. Less well established data such as awakening seizures in TLE patients, lateralization value of facial wiping (ipsilateral to the focus), statistically significant associations between behavioral pairs (dyads), and new behavioral sequences in TLE were also observed. We suggest that Neuroethology also has great potential in the study of human epilepsy semiology. This work had an important role in method standardization for human epilepsy, setting the basis for the development of future clinical studies including correlation with other diagnostic methods (EEG, magnetic resonance, and SPECT). The next step will be the comparative study of seizures of patients with left and right TLE, with a greater number of patients, and the development of a digital video library.

song learning behavior the interface with Neuroethology
Trends in Neurosciences, 1991Co-Authors: Peter MarlerAbstract:Abstract Behavioral studies of song learning in birds continue to raise new problems for neuroethological investigation. Evidence is emerging for a new form of vocal plasticity, called ‘action-based learning'. Motor patterns are overproduced during a particular phase of ontogeny, and are then subjected to attrition and selective reinforcement by various kinds of social stimulation as the young bird matures. This form of learning, analogous to operant conditioning, can occur at phases of development when the more traditional form of ‘memory-based learning' is no longer possible. There is evidence that different physiological mechanisms are involved in the development and the maintenance of mature singing, with a transition occurring at the time of song crystallization. Neural events associated with the developmental stabilization of motor patterns are worthy of more study.

Neuroethology what is it
Reference Module in Life Sciences#R##N#Encyclopedia of Animal Behavior, 2010Co-Authors: M KonishiAbstract:The goal of Neuroethology is to study the neural mechanisms of natural behavior. Stereotyped movements in animals led to the concept of central pattern generators, which are now known and well studied in many species. Control of movements by sensory feedback has also been shown in many systems and animals. Processing of biologically significant signals has also been an important subject in this field. Contrary to the idea of early ethologists who thought of mechanisms within the central nervous system, peripheral sensory cells and organs may be highly selective for biologically important stimuli. Neuroethological approaches have also revealed the nature of neural organizations in which successive stages of signal processing are carried out in some animal groups.

Neuroethology of sound localization in the owl
Journal of Comparative Physiology A-neuroethology Sensory Neural and Behavioral Physiology, 1993Co-Authors: M KonishiAbstract:The preface to "King Solomon's Ring" by Konrad Lorenz (1952) starts with the following poem by Rudyard Kipling. There was never a king like Solomon not since the world began Yet Solomon talked to a butterfly As a man would talk to a man.

Sensory Ecology and Neuroethology of the Lateral Line
Springer Handbook of Auditory Research, 2013Co-Authors: John C. Montgomery, Horst Bleckmann, Sheryl CoombsAbstract:The sensory ecology and Neuroethology of the lateral line provides an overview of the role of the lateral line in natural fish behaviour. The approach is more conceptual than comprehensive, choosing representative behaviors and especially those that lend themselves to a neuroethological analysis. This approach provides a clear focus for the determination of the relevant parameters of the physical stimulus, the physical and physiological mediation of stimulus encoding, and a targeted approach as to how the central nervous system processes and transforms sensory inputs to behavioral action. Like all major sensory systems, the lateral line makes an important contribution to the sensory capabilities of fish and aquatic amphibians and contributes to a wide range of core behaviors. This overview covers the role of the lateral line in: feeding, avoidance of predators, communication, hydrodynamic imaging, and orientation to slow and turbulent flows.

hearing and lateral line lateral line Neuroethology
Encyclopedia of Fish Physiology#R##N#From Genome to Environment, 2011Co-Authors: John C. Montgomery, Sheryl CoombsAbstract:Understanding lateral line function requires a background of lateral line anatomy combined with carefully crafted behavioral and neurophysiological studies. This combination, called Neuroethology, provides the best insight into how an unfamiliar sensory system generates biologically useful information, and how this information guides behavior.
