Researched in Barcelona: What an EEG study observed about scent and attention

by TP2 Redaktion in The TP2 Journal

How do people experience a fragrance? A laboratory in Barcelona investigated this question.

A fragrance first affects perception. This is precisely where an exploratory study conducted by the neuroscientific institute Starlab Barcelona with the TPdeux composition comes in.

One Question, One Lab

The study did not investigate whether a fragrance "does something," but rather how people experience it in the moment—accompanied by measurements of brain and heart activity.

The Setup

Fifteen participants experienced two conditions in random order: the TPdeux composition and pure water vapor as a control. During this, researchers recorded brain activity via a 19-channel EEG and heart activity (ECG). Subjective feelings were also assessed.

EEG activity under TP2: Delta, Theta, Beta, and Gamma increased

What Was Revealed

Under the TPdeux condition, researchers observed increased activity in several EEG frequency bands. Participants described their state as relaxed yet alert, with inward-directed attention—an image that reminded the authors of observations from meditation research. Heart rate did not differ significantly between the conditions.

Mood and activation: TP2 versus water control

What the Study Does Not Say

Honesty is important: This was an exploratory study with a small group of fifteen individuals. Observations regarding mood and well-being showed trends, not statistically significant effects. Health-related claims cannot be derived from this—nor are they intended here.

Frequently Asked Questions

Was TP2 medically tested?
No. The study was an exploratory neuroscientific investigation of fragrance experience, not a clinical efficacy study.

How many people participated?
Fifteen. A small group—the observations should be read with corresponding caution.

What does "exploratory" mean?
That the study gathers initial insights and opens questions, rather than providing conclusive proof.

Origin and Sustainability – why Corsica | TPdeux

Where something comes from tells you what it is. TPdeux is created in Corsica. This is no coincidence. The Scented Isle Corsica is known as the scented isle. Almost half of the island is covered in maquis — wild scrubland of myrtle, rosemary, thyme, and sage. The scent greets you as soon as you step off the plane. An Ancient Tradition The plants of the maquis have long been distilled in Corsica. Myrtle, immortelle, cistus, juniper. An island that understands scent as a craft. It is within this tradition that TPdeux is created — at the Les jardins de Bordeo manufactory. Why It Matters Origin is responsibility. A solid manufactory. Clear processes. A careful composition. Not a scent from everywhere. A scent from one place. Frequently Asked Questions Where is TPdeux made? In a manufactory in Corsica — Les jardins de Bordeo. Why Corsica? Corsica, the "scented isle," has a long tradition of distilling aromatic plants. What is the maquis? The wild, aromatic scrubland that covers large parts of Corsica — with myrtle, rosemary, thyme, and more.

Mindfulness and Fragrance - Small Rituals for More Calmness | TPdeux

Peace rarely comes on its own. You invite it in. With a small, recurring gesture. A ritual. What a ritual is A ritual isn't a big deal. It's a conscious gesture that repeats itself. The first cup of tea. The open window in the morning. A scent that marks a moment. Scent as an anchor Smell and memory are closely linked. A scent can be a sign: It's break time now. Not loud. Not demanding. A quiet anchor in the day. Three small rituals Morning. Before the first screen lights up: a breath, a scent, a look outside. In between. Seven minutes unreachable. The diffuser on, the phone away. Evening. The transition from day to space. The light dimmed, the scent uplifted. Frequently Asked Questions How do I create a scent ritual? Choose a fixed moment in the day and connect it with a scent. Repetition creates the ritual. Which moment is suitable? In the morning before starting, a break at midday, or the transition into the evening. Why scent? Smell and memory are closely linked — a scent quickly brings a moment back.
