Asymmetric response properties of rapidly adapting mechanoreceptive fibers in the rat glabrous skin
Devecioğlu, İsmail; Güçlü, Burak (Informa Healthcare, 2013)Previous histological and neurophysiological studies have shown that the innervation density of rapidly adapting (RA) mechanoreceptive fibers increases towards the fingertip. Since the psychophysical detection threshold ... -
Bayesian prediction of psychophysical detection responses from spike activity in the rat sensorimotor cortex
Öztürk, Sevgi; Devecioğlu, İsmail; Güçlü, Burak (Springer, 2023)Decoding of sensorimotor information is essential for brain-computer interfaces (BCIs) as well as in normal functioning organisms. In this study, Bayesian models were developed for the prediction of binary decisions of 10 ... -
Correction to: Psychophysical detection and learning in freely behaving rats: a probabilistic dynamical model for operant conditioning (Journal of Computational Neuroscience, (2020), 48, 3, (333-353), 10.1007/s10827-020-00751-8)
Devecioğlu, İsmail; Güçlü, Burak (Springer, 2020)The original version of this article unfortunately has some typographical errors in equations (5), (6), (7), (8), and (12). Apparently, the corrections during the proofing stage were not accurately implemented; some equations ... -
Intracortical microstimulation for tactile feedback in awake behaving rats
Devecioğlu, İsmail; Öztürk, Sevgi; Güçlü, Burak (Elsevier, 2021)Cortical neuroprostheses aim to partially compensate for the loss of sensory and motor function in severe neurological conditions such as spinal cord injury or amyotrophic lateral sclerosis. Intracortical microstimulation ... -
Mechanical Impedance of Rat Glabrous Skin and Its Relation With Skin Morphometry
Gok, Caglar; Devecioğlu, İsmail; Güçlü, Burak (Asme, 2022)The mechanical impedance of intact and epidermis-peeled rat glabrous skin was studied at two sites (digit and sole) and at two frequencies (40 Hz and 250 Hz). The thicknesses of skin layers at the corresponding regions ... -
A novel vibrotactile system for stimulating the glabrous skin of awake freely behaving rats during operant conditioning
Devecioğlu, İsmail; Güçlü, Burak (Elsevier Science Bv, 2015)Background: Rat skin is innervated by mechanoreceptive fibers similar to those in other mammals. Tactile experiments with behaving rats mostly focus on the vibrissal system which does not exist in humans. The aim of this ... -
A Preliminary Model for Operant Conditioning of Rats in a Detection Task
Devecioğlu, İsmail; Güçlü, Burak (IEEE, 2016)In this study, we proposed a nonlinear probabilistic model to show how operant conditioning develops in rats trained to detect vibrotactile stimuli on their hindpaw glabrous skin. The model shows the dynamics of neural ... -
Psychophysical correspondence between vibrotactile intensity and intracortical microstimulation for tactile neuroprostheses in rats
Devecioğlu, İsmail; Güçlü, Burak (Iop Publishing Ltd, 2017)Objective. Recent studies showed that intracortical microstimulation (ICMS) generates artificial sensations which can be utilized as somatosensory feedback in cortical neuroprostheses. To mimic the natural psychophysical ... -
Psychophysical detection and learning in freely behaving rats: a probabilistic dynamical model for operant conditioning
Devecioğlu, İsmail; Güçlü, Burak (Springer, 2020)We present a stochastic learning model that combines the essential elements of Hebbian and Rescorla-Wagner theories for operant conditioning. The model was used to predict the behavioral data of rats performing a vibrotactile ... -
Real-Time Performance of a Tactile Neuroprosthesis on Awake Behaving Rats
Öztürk, Sevgi; Devecioğlu, İsmail; Beygi, Mohammad; Atasoy, Ahmet; Mutlu, Şenol; Özkan, Mehmed; Güçlü, Burak (IEEE-Inst Electrical Electronics Engineers Inc, 2019)With the advancement of electrode and equipment technology, neuroprosthetics have become a promising alternative to partially compensate for the loss of sensorimotor function in amputees and patients with neurological ... -
Vibrotactile Sensitivity of Freely Behaving Rats and Operant Conditioning by Intracortical Microstimulation
Devecioğlu, İsmail; Güçlü, Burak (IEEE, 2015)In this study, 5 adult Wistar albino rats were trained to detect presence or absence of mechanical vibrations applied on the volar surface of their hindpaws. Vibrotactile sensitivity of glabrous skin of these rats were ...
