“…In particular, the beta rhythm was synchronized with inspiration. A few years later, similar beta (20–30 Hz) band enhancement was found in the amygdala during odor delivery; but occurring at the transition between inhalation and exhalation, with the amplitude of these spindles correlated to the degree of olfactory stimulation (Ganzha, 1986). Since then, several studies have shown that not only beta but three main frequency bands are represented during olfactory processing in the primary olfactory cortex: theta, beta, and gamma (Arabkheradmand et al., 2020; Jiang et al., 2017; Jung et al., 2006; Paulsen & Sejnowski, 2006; Yang et al., 2022; Zhou et al., 2019).…”

Brain activity may manifest itself as oscillations which are repetitive rhythms of neuronal firing. These local field potentials can be measured via intracranial electroencephalography (iEEG). This review focuses on iEEG used to map human brain structures involved in olfaction. After presenting the methodology of the review, a summary of the brain structures involved in olfaction is given, followed by a review of the literature on human olfactory oscillations in different contexts. A single case is provided as an illustration of the olfactory oscillations. Overall, the timing and sequence of oscillations found in the different structures of the olfactory system seem to play an important role for olfactory perception.

“…The amygdalae are involved in orienting to smells and sounds (Ursin and Kaada, 1960a , b ; Ganzha, 1986 ; Zald and Pardo, 1997 ; Sobel et al, 1999 ) as much as in orienting to visual stimuli. Hence, we predict that aesthetic evaluation of music, food, mathematical formulae (Zeki et al, 2014 ) and maybe even of sculptures or surfaces that can only be felt (e.g., in complete darkness) will also (besides visual textures and shapes) differentially involve the amygdala.…”

It has been proposed that the top-down guidance of feature-based attention is the basis for the involvement of the amygdala in various tasks requiring emotional decision-making (Jacobs et al., 2012a). Aesthetic judgments are correlated with particular visual features and can be considered emotional in nature (Jacobs et al., 2016). Moreover, we have previously shown that various aesthetic judgments result in observers preferentially attending to different visual features (Jacobs et al., 2010). Here, we argue that—together—this explains why the amygdalae become active during aesthetic judgments of visual materials. We discuss potential implications and predictions of this theory that can be tested experimentally.
