Kolkata: In a tragic incident, a one-and-a-half-year old boy, who was travelling on her mother’s lap, died after falling from a moving auto-rickshaw.The incident took place on Tuesday morning at Vivek More in Baranagar. The victim’s mother, Rinki Sarkar, boarded the auto from Tobin Road and was going to Noapara. It was learnt that the baby fell from the vehicle when the auto-rickshaw was taking a sharp bend on AK Mukherjee road.Locals alleged that the vehicle was running at a high speed and this led to the incident. The victim’s mother got down from the vehicle after her son fell on the road. The auto-rickshaw driver fled the spot immediately after the incident. Locals rushed the victim to Baranagar State General Hospital where the doctors pronounced him brought dead. The victim had received severe head injuries after falling from the speeding vehicle.

London: Despite their small brains, pigeons are capable of switching between two tasks as quickly as humans – and even quicker in certain situations, new research has found. The researchers believe that the cause of the slight multitasking advantage in birds is their higher neuronal density.For the study, published in the journal Current Biology, the researchers performed the same behavioural experiments to test birds and humans. “For a long time, scientists used to believe the mammalian cerebral cortex to be the anatomical cause of cognitive ability; it is made up of six cortical layers,” said Sara Letzner from Ruhr-Universitat Bochum in Germany.

In the experiment, both the human and the avian participants had to stop a task in progress and switch over to an alternative task as quickly as possible. “Researchers in the field of cognitive neuroscience have been wondering for a long time how it was possible that some birds, such as crows or parrots, are smart enough to rival chimpanzees in terms of cognitive abilities, despite their small brains and their lack of a cortex,” Letzner said. The results of the current study suggest that it is precisely because of their small brain that is densely packed with nerve cells that birds are able to reduce the processing time in tasks that require rapid interaction between different groups of neurons.
