Karl Geiger Unveils Device That Reads Your Thoughts, Shocking the Science World.

**Karl Geiger Demonstrates Thought‑Reading Apparatus at International Neuroscience Conference**

Berlin – Amid thunderous applause and stunned silence, neuroscientist Karl Geiger unveiled a portable brain‑interface prototype that can translate neural signals into perceptible user intent at the research room’s front podium on Thursday. The device, nicknamed 'MindScope,' employs a dense array of micro‑electrodes and machine‑learning algorithms trained on millions of neural patterns to decode basic cognitive states in near real‑time.

During the demonstration, a volunteer marked from the audience tapped a word on a screen without speaking, and the device rendered the chosen term within two seconds—an outcome that has sparked debate among ethicists, data‑privacy advocates, and fellow scientists. Geiger’s team claims accuracy rates exceeding 85 % for simple commands, while acknowledging limitations with complex thoughts or emotional nuance.

'This is a proof of concept,' Geiger said. 'We’re turning observed brain activity into tangible information, but the technology is still in early developmental stages.' The presentation was accompanied by a brief virtual tour of the sensor array, highlighting how its high‑density configuration obtains a finer resolution of cortical spiking activity than current non‑invasive electrodes.

Industry analysts warn that commercial deployment could face regulatory hurdles, especially concerning the safety of prolonged usage and the potential for unauthorized data capture. Meanwhile, privacy law experts in the EU have called for immediate scrutiny under the General Data Protection Regulation (GDPR). Some scholars argue that such devices could revolutionize neuroprosthetics, offering communication channels for individuals with locked‑in syndrome or motor impairments. Others point out the philosophical implications for free will and mental privacy.

In a closed session, Geiger’s lab disclosed that the machine leverages deep neural networks trained in a two‑phase process: an unsupervised feature extraction phase and a supervised classification phase. The lab also teased a second version aimed at distinguishing emotional valence from neutral thought, a development that could alter therapeutic practices in psychiatry.

As word of the unveiling circulates across scientific circles, researchers anticipate a wave of skepticism and excitement. The device’s potential to decode thought is poised to redraft the boundaries between mind, machine, and society, raising both awe and caution in equal measure.
