BACKGROUND Today, there is an increasing need to centralize and standardize electronic health data within clinical research as the volume of data continues to balloon. Domain-specific common data elements (CDEs) are emerging as a standard approach to clinical research data capturing and reporting. Recent efforts to standardize clinical study CDEs have been of great benefit in facilitating data ...

Electrocorticography (ECoG) constitutes a powerful and promising neural recording modality in humans and animals. ECoG signals are often decomposed into several frequency bands, among which the so-called high-gamma band (80-250Hz) has been proposed to reflect local cortical functions near the cortical surface below the ECoG electrodes. It is typically assumed that the lower the frequency bands,...

Thyme essential oil (TEO) was extracted from dried leaves of Thymus vulgaris. The air-dried aerial parts the plant produced 1.0% yield TEO. detection this oil’s compounds performed by GC-MASS. cytotoxic activity TEO evaluated against two human cancer cell lines, namely HeLa (human epithelial cervical cancer) and MCF-7 breast carcinoma). Cells grown in 96 multi-well plates were treated with six ...

Directing attention to a behaviorally relevant visual stimulus can overcome the distracting effects of other nearby stimuli. Correspondingly, physiological studies indicate that attention serves to filter distracting stimuli from receptive fields (RFs) in several extrastriate areas. Moreover, a recent study demonstrated that lesions of extrastriate areas V4 and TEO produce impairments in attent...

The frontal eye field (FEF) contributes to directing visual attention and saccadic eye movement through intrinsic processing, interactions with extrastriate visual cortical areas (e.g., V4), and projections to subcortical structures (e.g., superior colliculus, SC). Several models have been proposed to describe the relationship between the allocation of visual attention and the production of sac...

Neocortical pyramidal cells are characterized by markedly different structure among cortical areas in the mature brain. In the ventral visual pathway of adult primates, pyramidal cells become increasingly more branched and more spinous with anterior progression through the primary (V1), second (V2), and fourth (V4) visual areas and cytoarchitectonic areas TEO and TE. It is not known how these r...

Abstract Single crystals of the two alkali metal zinc oxidotellurates(IV), Rb 2 Zn(TeO 3 )(CO )·H O and Na Zn Te 4 11 , were obtained by reactions mixtures ZnO, TeO CO (molar ratios 2:3:6) 2:3:10), respectively, with small amounts water as a mineralizer. Both compounds crystallize order-disorder (OD) structures layers feature high stacking fault probability. The crystal structure is composed ex...

We describe the operation of a midbrain neural circuit in pigeons that may participate in selecting and attending to one visual stimulus from the myriad displayed in their visual environment. This mechanism is based on a topographically organized cholinergic signal reentering the optic tectum (TeO). We have shown previously that, whenever a visual stimulus activates neurons in a given tectal lo...

We propose a novel approach aimed at adaptively setting the threshold of the smoothed Teagor energy operator (STEO) detector to be used in extracellular recording of neural signals. Many types of spike detectors have been proposed all with their advantages and drawbacks. Most of the times there is a trade off between simplicity and performance. The performance of such systems is generally gauge...

Birds have two main visual pathways to the telencephalon: the thalamofugal and tectofugal pathways. In the thalamofugal pathway in the chicken (Gallus gallus), neurons on each side of the thalamus receive visual afferents from the contralateral retina and project to either the ipsilateral or contralateral Wulst of the telencephalon. These projections are organized asymmetrically: there are more...
