Few years ago, OceanGate Expeditions faced several warnings of potentials for ‘catastrophic’ problems as it prepared for its ‘hallmark’ mission of taking wealthy passengers to tour the Titanic’s wreckage, a media report revealed.

It was January 2018, when OceanGate’s director of marine operations, David Lochridge filed a lawsuit after the company fired him for sparking “serious safety concerns about the design of the untested experimental model of Titan, the company’s submersible.”

According to The New York Times, David Lochridge was working on a report around that time, ultimately producing a document in which he said the craft needed more testing and stressed “the potential dangers to passengers of the Titan as the submersible reached extreme depths.”

In the documents, Lochridge reported learning that the viewport that lets passengers see outside the craft was only certified to work in depths of up to 1,300 meters, although OceanGate was planning to take tourists to nearly 4,000 meters below the ocean’s surface.

The lawsuit document also pointed out that “OceanGate refused to pay the cost of a viewport that meets the targeted depth (4,000 meters) to the company building the submersible.”

“The paying passengers would not be aware, and would not be informed, of this experimental design,” lawyers for Lochridge wrote in a court filing.

Instead of looking into Lochridge’s concerns, or fixing the submersible, the company fired and sued him for violating an agreement of not sharing confidential information outside the company.

OceanGate has said in court records that “he was not an engineer, that he refused to accept information from the company’s engineering team and that acoustic monitoring of the hull’s strength was better than the kind of testing that Mr. Lochridge felt was necessary.”

Two months later, OceanGate faced similarly dire calls from more than three dozen people — industry leaders, deep-sea explorers and oceanographers — who warned in a letter to its chief executive, Stockton Rush, that the company’s “experimental” approach and its decision to forgo a traditional assessment could lead to potentially “catastrophic” problems with the Titanic mission, which might have heavy consequences that affect every person in this industry.

“While this may demand additional time and expense, it is our unanimous view that this validation process by a third-party is a critical component in the safeguards that protect all submersible occupants,” the signatories wrote.

Rush responded that “the industry standards were stifling innovation. Titan craft was so innovative, it could take years to get it certified by the usual assessment agencies.”

Rush is one of five people onboard of the submersible.

Rescue teams from Canada, France, and the U.S. have been racing to find the submersible, which disappeared near the wreck of the Titanic, nearly 4,000 meters below the ocean’s surface, in the north Atlantic.

In February, a couple in Florida sued Rush, saying that his company refused to refund them the $105,000 that they each paid to visit the Titanic on the Titan in 2018. The trip was postponed several times, according to the suit, in part because the company said it needed to run more tests on the Titan. The couple claimed that Rush reneged on his promise of giving them a refund and that the company instead demanded that they participate in a July 2021 voyage to the wreckage.

In a court filing last year, OceanGate referenced some technical issues with the Titan during the 2021 trip.

“On the first dive to the Titanic, the submersible encountered a battery issue and had to be manually attached to its lifting platform,” the company’s legal and operational adviser, David Concannon, wrote in the document. The submersible sustained ‘modest’ damage to its exterior, he wrote, leading OceanGate to cancel the mission so it could make repairs.

Still, Concannon wrote in the filing, 28 people were able to visit the Titanic wreckage on the Titan last year.

Consciousness is at the center of human existence, the ability to see, hear, dream, imagine, feel pain or pleasure, dread, love and more. But where precisely does this reside in the brain? That is a question that has long confounded scientists and clinicians. A new study is offering fresh insight.

In a quest to identify the parts of the brain underpinning consciousness, neuroscientists measured electrical and magnetic activity as well as blood flow in the brains of 256 people in 12 laboratories across the United States, Europe and China, while the participants viewed various images. The measurements tracked activation in various parts of the brain.

The researchers found that consciousness may not arise in the "smart" part of the brain - the frontal areas where thinking is housed, which progressively grew in the process of human evolution - but rather in the sensory zones at the back of the brain that process sight and sound.

"Why is any of this important?" asked neuroscientist Christof Koch of the Allen Institute in Seattle, one of the leaders of the study published this week in the journal Nature.

"If we want to understand the substrate of consciousness, who has it - adults, pre-linguistic children, a second trimester fetus, a dog, a mouse, a squid, a raven, a fly - we need to identify the underlying mechanisms in the brain, both for conceptual reasons as well as for clinical ones," Koch said.

The subjects in the study were shown images of people's faces and various objects.

"Consciousness is the way it feels like to see a drawing of a toaster or Jill's face. Consciousness is not the same as the behavior associated with this feeling, for example pushing a button or saying, 'I see Jill,'" Koch said.

The researchers tested two leading scientific theories about consciousness.

Under the Global Neuronal Workspace Theory, consciousness materializes in the front of the brain, with important pieces of information then broadcast widely throughout the brain. Under the Integrated Information Theory, consciousness emanates from the interaction and cooperation of various parts of the brain as they work collectively to integrate information that is consciously experienced.

The findings did not square with either theory.

"Where are the neuronal footprints of consciousness in the brain? Very crudely put, are they in the front of the cortex - the outermost layer of the brain - such as the prefrontal cortex, as predicted by the Global Neuronal Workspace Theory?" Koch asked.

It is this prefrontal cortex that makes our species uniquely human, driving higher-order cognitive processes such as planning, decision-making, reasoning, personality expression, and moderating social behavior.

"Or are the footprints in the back regions of the cortex, the posterior cortex?" Koch asked. The posterior cortex houses the regions where hearing and vision processing occurs.

"Here, the evidence is decidedly in favor of the posterior cortex. Either information pertaining to the conscious experience couldn't be found in the front or it was far weaker than in the back. This supports the idea that while the frontal lobes are critical to intelligence, judgment, reasoning, etc., they are not critically involved in seeing, in conscious visual perception," Koch said.

However, the study did not identify enough connections that last for as long as the conscious experience in the back of the brain to uphold the Integrated Information Theory.

There are practical applications in gaining a deeper understanding of the mechanics of consciousness in the brain.

Koch said it would be important for how doctors deal with patients in a coma or patients in a vegetative state or with unresponsive wakefulness syndrome, when they are awake but present no signs of awareness due to traumatic brain injury, stroke, cardiac arrest, a drug overdose or other causes.

"If the patient remains in this unresponsive state for longer than a few days without signs of recovery, the clinical team initiates discussion with the family around, 'Is this what they would have wanted?'" Koch said.

Of such patients, 70% to 90% die because a decision has been made to withdraw life-sustaining treatment.

"However, we now know that around a quarter of patients in either coma or vegetative state/unresponsive wakefulness syndrome are conscious - covert consciousness - yet are unable to signal this at the bedside," Koch said, referring to research published last year in the New England Journal of Medicine. "Knowing about the footprints of consciousness in the brain will let us better detect this covert form of 'being there' without being able to signal."
