Physical activity increases the flow of blood to the brain, which requires large amounts of oxygen. Bob Jacobs, CC BY-NDīrain health is also affected by living in small quarters that don’t allow for needed exercise. As a result, the cortical neurons in captive animals process information less efficiently than those living in enriched, more natural environments.Īn actual cortical neuron in a wild African elephant living in its natural habitat compared with a hypothesized cortical neuron from a captive elephant. Neurons become smaller, and their dendrites – the branches that form connections with other neurons – become less complex, impairing communication within the brain. Capillaries shrink, depriving the brain of the oxygen-rich blood it needs to survive. Subsisting in confined, barren quarters that lack intellectual stimulation or appropriate social contact seems to thin the cerebral cortex – the part of the brain involved in voluntary movement and higher cognitive function, including memory, planning and decision-making. Impoverishment results in thinning of the cortex, a decreased blood supply, less support for neurons and decreased connectivity among neurons. This illustration shows differences in the brain’s cerebral cortex in animals held in impoverished (captive) and enriched (natural) environments.
In decades of studying the brains of humans, African elephants, humpback whales and other large mammals, I’ve noted the organ’s great sensitivity to the environment, including serious impacts on its structure and function from living in captivity. Unfortunately, these are common conditions for many large, captive mammals in the “entertainment” industry. To combat stress and boredom, she swims in slow, endless circles and has gnawed her teeth to the pulp on her concrete pool. Orcas are social animals that live in family pods with up to 40 members, but Kiska has lived alone in a small tank since 2011. Kiska, a young female orca, was captured in 1978 off the Iceland coast and taken to Marineland Canada, an aquarium and amusement park.
Hanako was solitary for the last decade of her life. In the wild, elephants live in herds, with close family ties.

The heart valves were received by NH Bengaluru and the liver by Apollo BGS Hospitals, Mysuru.
While one kidney was received by the Apollo BGS Hospitals, the other one was received by the NH Bengaluru. on November 11, Hemanth’s organs – heart valves, kidneys, and liver - were retrieved at the hospital. The deceased patient’s uncle, brother and relatives came forward to donate his organs,” the hospital said.Īs per the organ donation protocol, officials from Jeeva Sarthakathe, which was earlier known as ZCCK, initiated the process in accordance with organ recipients’ waiting list. The patient’s family was counselled for organ donation as per the defined protocol. Hemanth was healthy before the incident and further tests confirmed his eligibility for organ donation. However, on the third day (on November 10), Hemanth was declared brain dead due to brain stem failure. He was shifted to ICU on November 8 at 2.20 p.m, a release from the hospital said.Īs the patient was in critical condition, he was put on life support for two days. Initial CT scan showed cervical spine and brain stem injuries and the patient underwent surgery for the same. as per the advice of the doctors at the Mandya Government Hospital after giving him first aid for some injuries. Hemanth was shifted to Apollo BGS Hospitals here on November 4 around 2.30 p.m. A 27-year-old man, who was declared brain dead, has saved the lives of four persons by donating his organs, in Mysuru.
