Dog brains have sense of quantity and knack for numbers: Study

A recent study reveals that dogs have an innate sense of quantity same way humans do and may even take tice when one put fewer treats in ir bowl. According to research, dogs naturally process numbers in a similar brain region as humans. study also suggests a knack of numbers is present in even untrained dogs and y could have deep evolutionary roots. A psychologist at Georgia State University who wasn’t involved in research, Michael Beran reportedly said that study also supports idea that ways in which animals process quantity in ir brains maybe 'ancient and widespre among species'. 

According to international media reports, Gregory Berns, a neuroscientist at Emory University in Atlanta recruited 11 dogs from various breeds, including border collies, pitbull mixes, and Labror golden retriever mixes to see wher y could find brain activity associated with a sensitivity to numbers. To conduct study team of scientists h ir subjects enter scanner, rest ir hes on a block, and fix ir eyes on a screen at opposite end. According to reports, screen was an array of light grey dots on a black background whose number changed every 300 milliseconds. scientists said that eight out of 11 dogs passed test, furr ded that slightly different brain regions lit up in each dog, likely because y were different breeds.

Children exposed to dogs less likely to develop schizophrenia 

In ar study, exposure to dogs from an early is linked to a reduced risk of developing schizophrenia - as much as 24% - later in life, according to a US-based research study from John Hopkins Children Centre in Washington. Robert Yolken, MD from John Hopkins Children Centre and primary researcher on study told ncies and journal that: "Serious psychiatric disorders have been associated with alterations in immune system linked to environmental exposures in early life, and since household pets are often among first things with which children have close contact, it was logical for us to explore possibilities of a connection between two."

A cat or a dog can strengn immune system of a young child plausible to hereditary schizophrenia through allergic reactions and microbe exposure apart from influencing changes in a person’s affective and neurochemistry.
