Can our brain form false memories?

I keep working on to disseminate knowledge about neuroscience during these special times. Today I assisted the first “One World Cognitive Psychology Seminar”, a weekly online seminar in Zoom featuring a presentation by a stellar cognitive psychologist followed by a discussion open to anyone around the world. The seminar time is Tuesdays 17:15 – 18:45 Central European…

Is working memory closely related to attention?

This week at my research group seminar we’ve discussed the following paper about how attention is closely linked to working memory, which is related to another post about a Taxonomy of Attention that I wrote a year ago based on the paper by Chen et al. (2011): J Cogn. 2019; 2(1): 36. Published online 2019 Aug…

Why have we lost so much short-term memory capacity compared to chimpanzees?

The answer is in this Twitter threat by Brian Roemmele: Consider: millions of years ago our antecedents gave a massive sacrifice of their left hemisphere. We lost a tremendous amount of short term memory and replaced it with Broca’s, Wernicke & the phonological loop. But why? So we can—talk. Thus chimpanzees can do this—we can’t:…

How do we create memories?

Have you ever thought about how our brain registers all the memories that we live? How we are able to easily recall a memory from the past like as it had happened yesterday? Or why do we remember so many details (or not) of the most important days in our lives? I recently watched an…

A taxonomy of attention

In 1890, William James famously declared in The Principles of Psychology that “Everyone knows what attention is”. Attention has become a catch-all term for how the brain processes its own information, and its effects can be measured through behaviors, electrophysiology, and brain imaging methods. However, attention is so ubiquitous and has such multiple forms that it is…

How human memory works?

Memory is essential to all our lives. Without a memory of the past, we could not operate in the present or think about the future. We would not be able to remember what we did yesterday, what we have done today or what we plan to do tomorrow. Without memory, we could not learn anything….

Brain signals, a new biometric identification

Fingerprint scanning, iris scanning, and voice stress analyzer are dated technology compared to the latest form of biometric authentication: the brain’s semantic memory. A team led by postdoctoral researcher Blair Armstrong of the Basque Center for Cognition, Brain, and Language in Spain, observed that the brain signals of 45 participants reading a list of 75…

How the Brain Builds Memory Chains

Do you remember the first time you met your college classmate? You were probably nervous, talking a little too loudly and laughing a little too heartily. What else does that memory bring to mind? The lunch you shared later? The other classmates you met that night? Memories bring about memories, and as soon as you…
