Summary: The anterior temporal lobe (ATL) is a central hub for interpreting social hierarchies and facial emotions, and new neuroimaging work links its function to anxiety and mood processes. By applying improved imaging methods, researchers overcame previous technical obstacles and found robust ATL engagement when people make social or emotional judgments.
The study suggests that anxiety can alter the balance between semantic (meaning-based) and emotional processing in the ATL. Ongoing analyses focus on mapping the ATL’s structural and functional connections and investigating possible sex differences in these mechanisms.
Key Facts:
- ATL’s Role: The anterior temporal lobe supports semantic and social-emotional meaning-making, enabling interpretation of social hierarchy and facial expressions.
- Anxiety Link: Individuals with higher anxiety show increased ATL activation, consistent with altered emotional interpretation of social cues.
- Future Focus: Mapping structural pathways, such as the uncinate fasciculus, and completing functional connectivity analyses will help clarify how ATL interactions contribute to anxiety and guilt.

Understanding how the brain interprets social hierarchy and facial emotions could be key to advancing knowledge of anxiety and mood disorders.
This work is led by Maya Visser at Universitat Jaume I in Castelló. Her project examines the anterior temporal lobe’s role within the broader brain network responsible for assigning meaning to social and emotional concepts. The team combines refined functional magnetic resonance imaging (fMRI) methods with behavioral tasks to probe how semantic and emotional systems interact.
Historically, the ATL has been difficult to study using fMRI because of geometric distortions that degrade the signal in this region. The Neuropsychology and Functional Neuroimaging (NFN) group at Universitat Jaume I has implemented specific acquisition and analysis strategies to mitigate these issues, enabling clearer measurement of ATL activity during social and emotional tasks.
Funded by the 2021 National Plan for Scientific Research, the project explores how the ATL communicates with frontal and limbic regions when people interpret social situations or express emotions. It also examines how these networks differ in individuals with varying degrees of subclinical anxiety — anxiety levels that do not meet diagnostic thresholds but still influence cognition and brain function.
Preliminary analyses indicate that the upper ATL shows strong activation when participants evaluate social hierarchies or decide based on emotional facial expressions. These analyses also reveal greater ATL activation in people reporting higher anxiety levels, suggesting anxiety may bias interpretation of social concepts toward negative affect. In such cases, coordination between the ATL-driven semantic system and the emotional system appears disrupted. These initial findings have been submitted to peer-reviewed journals.
Key next steps include completing detailed functional and structural connectivity analyses to map pathways linking the ATL with other regions. One focus is the uncinate fasciculus, a white-matter tract connecting the ATL to the orbitofrontal cortex; this pathway could be critical for integrating semantic meaning with emotional valuation, and therefore relevant for feelings such as guilt and anxiety.
Methodologically, the team is also working to secure a gender-balanced sample to allow accurate assessment of sex differences in ATL function and its relation to anxiety and emotional processing.
Maya Visser is a Ramón y Cajal researcher in the Department of Basic and Clinical Psychology and Psychobiology at Universitat Jaume I. She has contributed to neuroimaging projects across the UK, the Netherlands and Spain, focusing on semantic processing and its role in social and emotional behavior. The NFN group applies interdisciplinary neuroimaging and experimental approaches to study brain mechanisms in healthy and clinical populations, with applications to psychology, neurology, education and marketing.
With this initiative, Universitat Jaume I emphasizes research that links fundamental brain science to mental health applications. Studies of the ATL and its networks offer new perspectives for understanding how people think, feel and interact, and they may help guide interventions that target the roots of emotional disorders.

Title: “Subjective sleep quality in healthy young adults moderates associations of sensitivity to punishment and reward with functional connectivity of regions relevant for insomnia disorder” by Maya Visser et al. SLEEP
Abstract
Subjective sleep quality in healthy young adults moderates associations of sensitivity to punishment and reward with functional connectivity of regions relevant for insomnia disorder
Chronic poor sleep is a major risk factor for mood and anxiety disorders, yet individual susceptibility to affective changes after sleep disruption is not fully understood. Prior evidence suggests that brain activity during emotional processing may modulate this vulnerability. To investigate, the authors performed whole-brain resting-state functional connectivity analyses in a large cohort of healthy young adults (N = 155).
Using regions consistently implicated in insomnia as seed regions, the study assessed sleep quality–related connectivity patterns and how these patterns interact with individual measures of reward and punishment sensitivity, as well as indices of emotional health. Most findings reflected interactions between sleep quality and reinforcement sensitivity, with opposite associations observed in good versus poor sleepers.
For example, connectivity between precentral gyrus and posterior insula was negatively associated with trait anxiety, with the lowest coupling found in poor sleepers who were highly sensitive to punishment. Another result tied sleep quality alone to coupling between the subgenual anterior cingulate cortex and thalamus, a pattern also related to habitual use of emotion suppression strategies.
Overall, the study supports the idea that reinforcement sensitivity is an important moderator of how poor sleep quality relates to brain connectivity and emotional health, offering clues about why some individuals are more prone to sleep-related affective dysregulation.
