recommendations! Published in 2022 at "Annals of Clinical and Translational Neurology"

DOI: 10.1002/acn3.51620

Abstract: Recently, we showed that resection of at least 27% of the temporal part of piriform cortex (PiC) strongly correlated with seizure freedom 1 year following selective amygdalo‐hippocampectomy (tsSAHE) in patients with mesial temporal lobe epilepsy (mTLE).… read more here.

DOI: 10.1002/acn3.52176

Abstract: The piriform cortex is considered to be highly epileptogenic. Its resection during epilepsy surgery is a predictor for postoperative seizure freedom in temporal lobe epilepsy. Epilepsy is associated with a dysfunction of the blood–brain barrier.… read more here.

DOI: 10.1002/hbm.26274

Abstract: The piriform cortex (PC) is located at the junction of the temporal and frontal lobes. It is involved physiologically in olfaction as well as memory and plays an important role in epilepsy. Its study at… read more here.

DOI: 10.1007/s00429-018-1741-y

Abstract: The anterior commissure (AC) is a phylogenetically conserved inter-hemispheric connection found among vertebrates with bilateral symmetry. The AC connects predominantly olfactory areas but many aspects of its development and structure are unknown. To fill this… read more here.

DOI: 10.1016/j.neuroimage.2021.117782

Abstract: INTRO The human sense of smell is highly individual and characterized by a strong variability in the perception and evaluation of olfactory stimuli, depending on cultural imprint and current physiological conditions. Since this individual perspective… read more here.

DOI: 10.1016/j.neuroimage.2021.118130

Abstract: Neuronal oscillations route external and internal information across brain regions. In the olfactory system, the two central nodes-the olfactory bulb (OB) and the piriform cortex (PC)-communicate with each other via neural oscillations to shape the… read more here.

DOI: 10.1016/j.tox.2019.05.007

Abstract: The detrimental effects of organophosphate (OP) nerve agents have been reported but the mechanisms mediating these multiple effects are not well understood. Recent use of nerve agents in Syria and the UK illustrate their continuous… read more here.

DOI: 10.1038/s41467-024-45161-x

Abstract: Sensory perception depends on interactions between external inputs transduced by peripheral sensory organs and internal network dynamics generated by central neuronal circuits. In the sensory cortex, desynchronized network states associate with high signal-to-noise ratio stimulus-evoked… read more here.

DOI: 10.1038/s41586-021-03628-7

Abstract: Perceptual constancy requires the brain to maintain a stable representation of sensory input. In the olfactory system, activity in primary olfactory cortex (piriform cortex) is thought to determine odour identity1-5. Here we present the results… read more here.

DOI: 10.1038/s41598-024-56996-1

Abstract: Olfactory dysfunction is a common feature of both postviral upper respiratory tract infections (PV) and idiopathic Parkinson’s disease (PD). Our aim was to investigate potential differences in the connectivity of the posterior piriform cortex, a… read more here.

DOI: 10.1073/pnas.2501811122

Abstract: Significance The neural response to a specific stimulus often evolves over time in a phenomenon known as representational drift (RD). However, the underlying mechanisms driving this widespread phenomenon remain poorly understood. By employing a realistic… read more here.
