Interictal spike detection is a time-consuming, low-efficiency task, but is important to epilepsy diagnosis. Automated systems reported to date usually have their practical efficacy compromised by elevated rates of false-positive detections per minute, which are caused mainly by the influence of artifacts (such as noise activity and ocular movements) and by(More)
We present a software (ETHOWATCHER(®)) developed to support ethography, object tracking and extraction of kinematic variables from digital video files of laboratory animals. The tracking module allows controlled segmentation of the target from the background, extracting image attributes used to calculate the distance traveled, orientation, length, area and(More)
This study investigated the effect of GABAA (muscimol, MUSC) and GABAB (baclofen, BACL) agonist receptors microinjected into medial accumbens shell on feeding and the level of fear in free-feeding rats submitted to the elevated plus-maze (EPM), an animal model of anxiety. Bilateral microinjections of either MUSC (128 pmol/0.2 microl/side) or BACL (128 and(More)
Serotonergic neurons in the median raphe nucleus (MnR) are stimulated by alpha(1)-adrenergic agonists and inhibited by alpha(2) agonists. This study investigated the participation of MnR alpha(2)-adrenergic receptors in the control of anxiety-like behavior and feeding as an attempt to establish a functional association between these behaviors. The(More)
This study investigated the role of MnR α₁-adrenergic receptors in the control of anxiety-like and feeding behaviors and attempted to reveal a possible functional association between both behaviors. The α₁-adrenergic agonist phenylephrine (PHE) (at doses of 0.2, 2, 6, 20 nmol) or saline was injected into the MnR or into the pontine nucleus (Pn) of(More)
The effect of the gradient of luminosity between the open and the enclosed arms (O/E(DeltaLux)) of the elevated plus maze (EPM), upon the level of fear/anxiety in rats submitted to the trial 1/trial 2 paradigm was investigated. Male Wistar rats were assigned to freely explore either of three EPM configuration, with the enclosed arm walls constructed with(More)
This study investigated the effect of α-adrenoceptor agonists microinjected into the shell region of the accumbens nucleus (AcbSh) on feeding and anxiety-related behaviors in free-feeding rats. Male Wistar rats with a chronically implanted cannula into the AcbSh were unilaterally microinjected with either clonidine (CLON, α(2)-adrenoceptor agonist) or(More)
This study investigated the effect of the AMPA receptor antagonist 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX; 2.5 and 5.0 nmol/side) microinjected into the core and shell sub-regions of the accumbens (Acb) nucleus, on food intake and the level of anxiety in female rats. Bilateral microinjections of CNQX (5.0 nmol/side) into the Acb shell (AP, +1.08 to(More)
The possible involvement of central cholinergic neurotransmission in lipomobilization in avian species was investigated by injecting carbachol into the brain lateral ventricle (i.c.v.) of conscious pigeons (N = 9 per experimental group). I.c.v. injections of carbachol (27 nmol in 1 microliter) induced an intense increase (nearly 91% above baseline levels)(More)
