New research suggests the same brain areas may be involved in both detecting threats posed by animals and evaluating other humans&#8217; intentions. The study, published in the May 11 issue of the <em>Journal of Neuroscience<\/em>, offers insight into a basic feature of human cognition: how we understand and evaluate other creatures.<\/p>\n<div id=\"text\">\n<p>&#8220;<strong>The idea that animals may be processed in a similar way [to humans] and may piggyback on regions of the brain that have been implicated in social cognition suggests that those regions &#8230; are multipurpose<\/strong>,&#8221; said study author Andrew Connolly of Dartmouth College.<\/p>\n<p>Previously Connolly&#8217;s research group found that <strong>hierarchical classes of animals (say, bugs vs. mammals) are represented in an area of the brain called the lateral occipital complex, a region involved in object perception and recognition<\/strong>. What was not known, however, was which brain regions process information about an animal&#8217;s &#8220;dangerousness.&#8221;<\/p>\n<p>To investigate this, the researchers scanned volunteers&#8217; brains while they viewed pictures of bugs, reptiles, and mammals. <strong>Half of the animals depicted were classified as &#8220;low threat,&#8221; such as butterflies and rabbits, and half were &#8220;high threat,&#8221; such as snakes and cougars<\/strong>. Using functional magnetic resonance imaging (fMRI), the researchers determined which areas of the brain were active when participants viewed bugs, reptiles, and mammals, and when they viewed low- and high-threat animals. Researchers used these activity patterns to map how two kinds of information &#8212; taxonomic class and threat &#8212; are encoded in the brain.<\/p>\n<p>As before, they found taxonomic class was represented in the lateral occipital complex. <strong>Surprisingly, a different area of the brain represented threat<\/strong>. This area, called the superior temporal sulcus, is a fold in brain tissue running just above the ear, and previous research has implicated the region in understanding facial expressions and deciphering others&#8217; intentions. The researchers speculate that evaluating other humans and evaluating threats posed by animals may be related functions.<\/p>\n<p>Nikolaus Kriegeskorte, a neuroscientist at the University of Cambridge who studies visual object recognition and was not involved in the study, said this is interesting basic science. &#8220;<strong>Knowing what parts of the brain are involved in social cognition and how information processing works is relevant to our understanding of human brains, minds, and cultures<\/strong>.&#8221;<\/p>\n<p><strong>The researchers are planning future studies to examine how activity in these brain networks changes over time<\/strong>. The present study used fMRI, which measures changes in blood flow as a proxy of neural activity, a measure that is slow and inadequate for understanding temporal relationships. To address this, the researchers plan to incorporate electrical recordings of brain activity in their studies.<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Society for Neuroscience\u00a0media release: Assessing whether a fluffy bunny or a giant spider poses a threat to our safety happens automatically.
