The Connected Hippocampus, 1st Edition, Preface and Table of Contents: O’Mara & Tsanov (ISBN-13: 978-0444635495)

The Connected Hippocampus: Preface Available here (Elsevier) and here (Amazon). The hippocampus is an intriguing and anatomically remarkable structure: it is possessed of a remarkable curvilinear appearance in coronal section, and it is easy to spot in anatomical section with the naked eye in just about any mammalian species. A special and important function has been ascribed to it… Read More

Kindness – How do Children Become Kind?

[This is a non-technical piece I did for the Powering Kindness campaign on the development of kindness in children, and how it relates to changes in brain function]. It’s an age-old argument – are we born to be kind to others or do we learn to be kind to others? Across all societies, humans of all ages… Read More

Validation of the face-name pairs task in major depression: impaired recall but not recognition

Take-home Message: memory – and especially associative memory – is impaired in a wide variety of neuropsychiatric and neurological conditions. Face-name pair learning is a useful method to tap into deficits in associative memory; usefully, it is a task dramatically impaired by lesions of the extended hippocampal formation. Here, we show that patients with depression showed… Read More

Hippocampal Volume is Decreased in Adult-Onset Hypothyroidism.

Take-home message: We provide preliminary evidence that hypothyroidism results in structural deficits in the adult human brain. Decreases in volume in the right hippocampus were evident in patients with adult-onset overt hypothyroidism, supporting some of the findings in animal models. [Download the paper] Thyroid. 2013 Nov 8.

Suppressing the encoding of new information in memory: a behavioral study derived from principles of hippocampal function.

Take-home message: We show here that mixing tasks that involve executive control (the n-back task, requiring continual updating and discarding of information held presently ‘in mind’) inhibits dramatically performance on an explicit memory task (associative memory: face-name pair learning), but not performance on control recognition memory tasks. We therefore provide further behavioural evidence that memory subsystems… Read More
