The role of the m6A pathway on electrophysiological correlates of spatial memory in animal model of Alzheimer's disease
 Karkušová, Patrícia ; Telenský, Petr (advisor) ; Hromádka, Tomáš (referee)
Memory is one of the vital cognitive functions and can be divided into two categories, short-term memory and long-term memory. Long - term memory is further divided into explicit (declarative) for facts and events and implicit (non-declarative) memory, covering all other types of long-term memory. Alzheimer's disease is well known for a gradual loss of declarative memory and spatial orientation. It is one of the most common causes of dementia and affects tens of millions of people worldwide. The aim of our study was to determine the effect of inhibition of FTO demethylase on neuronal activity in a rat model of Alzheimer's disease (TgF344-AD) and a control strain (F344-CT), and evaluate the stability of spatial maps. We used tetrodes implanted in hippocampal CA1 subregion to record extracellular neuronal activity. Spiking activity was recorded in two spatially different conditions (familiar, unknown) twice, before and after applications of pharmacological inhibitor of FTO demethylase (MO-I-500). We have also evaluated remapping and map stability related to the application of MO-I- 500. We found the average frequency of neuronal firing rate increased in F344-CT rats in both familiar and novel environments after inhibitor administration, whereas increase in TgF344- AD rats was detected only in the novel...
