Aug 18, 2021 · Read time: 3 minutes. Researchers have made a frightful finding by teasing out the circuits involved in producing a fear response in the brain and identified a type of brain wave that coordinated this reaction. A white car meanders down an idyllic country lane.

Aug 1, 2016 · There was a main effect of spatial frequency from 206–240 ms (cluster threshold P < 0.01) and an emotion by spatial frequency interaction from 290–334 ms (cluster threshold P < 0.05).

High spatial frequency (HSF) information is processed pri- marily through the ventral visual processing stream from V1 and encodes the fine-grained texture of objects such as faces.
Nov 26, 2020 · In humans, components participating in the expectation of pain show EEG activation (ERS/ERD) in fear-related structures at frequencies from the delta to the gamma band (Figure 4, see Abbreviations 1) .

Our findings show that N170 emotional modulations are unaffected by expression-specific spatial frequencies. However, expression-specific spatial frequencies alter early and mid-latency ERPs. Most notably, the EPN to neutral expressions is boosted by adding fearful spectra-but not vice versa.
Aug 1, 2023 · Here we provide a roundtable discussion on the nature and biological bases of fear- and anxiety-related states, traits, and disorders. The discussants include scientists familiar with a wide variety of populations and a broad spectrum of techniques.
