Introduction

Integrating information from the senses and between them is essential for perception but how does the brain choose which information to combine and which to keep separate? Here we show how this issue can be resolved with proscription: In order to offer 'what not' information that drives the suppression of improbable perceptual interpretations some neurons respond best to unrealistic combinations of features. First we provide a model that accounts for resilient estimates in the presence of conflicting signals as well as enhanced perception when signals are consistent and therefore should be integrated [1-5].

Description

Our perception of the world around us is based on patchy sensory data that is frequently confused and always incomplete. The brain mixes a variety of impulses that are subject to various limitations to produce perception. For instance, determining the geometry of a nearby item may require combining data from many visual signals and modalities (such as perspective, shading, and texture) (e.g., size from vision and touch) . Observers overcome ambiguity and make more accurate judgments by integrating signal. strongest proof of how prehistoric creatures functioned and interacted with their environment comes from palaeoneurology the study of the brain in the fossil record and how it has changed through time. Based on the morphology of brain regions that are specifically responsible for processing sensory data and creating behaviour it is possible to deduce the behaviour and sensory capabilities of extinct animals. Other neural structures, such as the cranial nerves and membranous labyrinth which convey sensory and motor information to and from the brain and support the perception of movement and orientation, respectively are frequently included in palaeo neurological investigations The principle of appropriate mass, which asserts that the size of a brain region dedicated to a given function is directly connected with the amount of processing capacity required to execute that function enables estimations of sensory ability and behaviour based on the morphology of the brain. As a result, areas of the brain that need more processing capability are typically larger to accommodate more neurons.

The brain end cast is not a perfect representation of the brain in life because it also represents other soft-tissue structures housed within the endocrinal cavity that did not fossilise, such as the dura matter and vascular tissue, which did not fossilize. This correlation allows hypotheses to be made about the sensory ability of extinct animals based on the morphology of the brain; however these structures do not represent the brain in its ideal form. Despite this information on an extinct animal's endocrinal cavity can be used to infer its neurosensory capacities by comparing it to closely similar extant taxa, which enables the development of hypotheses about its behaviour and ecology As equilibrioception and auditory abilities are known to correlate with the anatomy of the membranous labyrinth, it can be used as a proxy for assessing these abilities. The semi-circular canal morphology and locomotors strategy and ecology have also been revealed to be correlated in numerous recent studies with phylogenetic ally distant lineages having converging ear morphologies as a result of comparable types of locomotion and ecology. Despite the fact that the relationship between canal morphology and ecology is widely understood, it must be noted that the relationship is not perfect and that some groups' canal shapes are known to be very changeable Despite this, general locomotors strategies or ecologies can still be inferred from descriptions of the labyrinth anatomy in extinct animals.

A description of Champsosaurus' endocrinal anatomy and a comparison of the inner ear with those of other taxa are required to ascertain whether their sensory anatomy reflects the adaptations for aquatic habits seen in other aquatic reptiles, despite the fact that Champsosaurus are widely acknowledged to be aquatic. A considerable phylogenetic signal has been seen in the shape of semicircular canals in numerous lineages, according to several studies13. Given that Choristodera's evolutionary position within Neodiapsida is poorly understood and that recent phylogenies have put Choristodera in a polytomy with Archosauromorpha and Lepidosauromorpha this has significant implications for Champsosaurus. Therefore, new information on the evolutionary position of Choristodera could be learned by contrasting the inner ear of Chapsosaurus with those of other neodiapsids.
