Deep brain stimulation (DBS) may help control seizures in individuals with medically intractable epilepsy who are not candidates for resective surgery. The current review focuses on some preclinical studies of DBS of the piriform cortex (PC), an area involved in the generation and maintenance of seizures, as a potential therapeutic option for refractory epilepsy. We also present findings suggesting the safety of low frequency stimulation (LFS) of the PC on memory. A variety of LFS parameters have been suggested as an effective treatment strategy for refractory epilepsy. In generalized epilepsy, however, recent studies suggest that LFS may exacerbate seizures and high frequency stimulation (HFS) might be an alternative. Hence, further studies are required to explore the potential therapeutic targets and proper stimulation parameters for the successful translation of DBS of the PC to the clinic.

Neuronal structural plasticity gives the adult brain the capacity to adapt to internal or external factors by structural and molecular changes. These plastic processes seem to be mediated, among others, by the action of the neurotransmitter serotonin through specific receptors (5-HTRs). Previous studies have shown that the maturation of granule cells in the hippocampus is mediated by 5-HT3.

The locus coeruleus (LC) plays a vital role in cognitive function through norepinephrine release. Impaired LC neuronal health and function is linked to cognitive decline during ageing and Alzheimer's disease. This study investigates age-related alterations in olfactory detection and discrimination learning, along with its reversal, in Long-Evans rats, and examines the effects of atomoxetine (ATM), a norepinephrine uptake inhibitor, on these processes.

The human brain is organized as a hierarchical global network. Functional connectivity research reveals that sensory cortices are connected to corresponding association cortices via a series of intermediate nodes linked by synchronous neural activity. These sensory pathways and relay stations converge onto central cortical hubs such as the default-mode network (DMN).

We aimed to assess neurodegenerative changes in the rhinencephalon via magnetic resonance imaging (MRI) and relate it to olfactory function and diabetic peripheral neuropathy (DPN) in adults with type 1 diabetes (T1D). Individuals aged 18-65 with T1D duration over 10 years and control healthy subjects underwent olfactory assessment using Sniffin'Sticks and brain MRI to assess volumetric measurements of the olfactory bulbs and piriform cortex thickness. 32 T1D (24 males) aged 43.

Objective: The piriform cortex (PC) plays a critical role in ictogenesis, where an excitation/inhibition imbalance contributes to epilepsy etiology. However, the epileptic dynamics of the gamma-aminobutyric acid (GABA) system and the precise role of GABAergic neurons within the PC in epilepsy remain unclear.

Methods: We combined Ca and GABA sensors to investigate the dynamics of Gad2-expressing neurons and GABA levels, and selectively manipulated GABAergic neurons in the PC through chemogenetic inhibition and caspase3-mediated apoptosis targeting Gad2 interneurons.
