Despite the anatomical specificity and clinical relevance of the case, highlighting the involvement of the hippocampus in memory and possibly the amygdala in apathy, its theoretical implications remained underappreciated due to contextual, theoretical, and political factors. Bekhterev's reluctance to endorse strict localization of cognitive functions, the dominance of associationist theories in Russian neuroscience, and his politically motivated erasure during Stalin's regime contributed to the case's historical neglect.

In this study, 92 patients were examined to determine which impairments continue to affect multiplication performance even in the chronic phase after a first-time unilateral left-hemispheric stroke. Our results revealed a strong association between impaired multiplication performance and the disconnection of left long-term memory (para)hippocampal areas from left frontal and right parietal regions. Thus, unlike previous findings in the acute stroke phase, our results in the chronic phase emphasize the importance of (para)hippocampal regions for successful multiplication performance. We suggest that the affected areas and connections in chronic patients with persistent multiplication problems not only indicate areas that are crucial for the relearning of arithmetic facts, but also those crucial for the learning of arithmetic facts in general.

The present study investigated whether predicted instruments are decoded from the EEG signal during omission to examine the specificity of prediction in the timbre dimension. Thirty-five participants listened to unfamiliar melodies with simple (high predictability) or complex (low predictability) timbre change rules while watching a silent movie. The EEG was recorded when a tone expected to be played by one of four specific timbres (celesta, electric piano, marimba, organ) was omitted.

However, the support vector machine was able to decode the type of musical timbre during omission better than random chance in the high predictability condition but not in the low predictability condition.
